I am currently working on a breeze home mod. I have removed most of the furniture and decorations and replaced them with new stuff. While doing this I did link them to their appropriate X markers. When I enter the home for testing everything I added is correctly in place, as is some of the older items. This is only with certain items, such as the table, a shelf and most of the older plates and cups.
I created this mod on a computer with very little saves and it tested fine. When I test it on a computer with a higher game time things aren’t so well.
Any idea what is causing this and how I can fix it?

less saves?

OR

move to a better house

the items are baked in your save game. this mostly concerns statics, that's why other stuff (misc, movable static etc) did as you wanted and these didn't.

you shouldn't get that effect if you test from a clean (without your mod) save

to make them go away in savegames (which you'll likely have to do in breezehome if anybody else should ever be able to use this) tie them to an enabling parent and disable that.

to move them, rather make duplicates in new places and disable originals, or you'd have to move them with a script.

This is what I was afraid of. I did a save several times without my mod installed, and the items still appear. The items in question have been removed completely from the cell as I was working on it. They are no longer part of the default Breezehome. And they are no longer linked to their original XMarkers, either.

With these items removed I am no longer able to do anything with them. I'm kinda at a loss.

you wouldn't need a save without your mod but one where you've never been in breezehome, my bad, sorry.

as for your deleted items:

don't do that.

especially never ever delete items with parents, linked refs or whatever, they got those for a reason, some script ... will try to use them, not find them and error.

for the ones you've deleted in your mod, get tes5edit, under your mod -> cells, you'll have your breezehome modifications. items you modified will be listed there with yellow background, items you added yourself just listed normally. among the yellowed ones are those you deleted, it'll also say "deleted" in their info. delete these records out, this deletes your delete, meaning it's back to normal.

edit: instead of tes5edit, you can of course also find your deleted entries in ck's detail window, should you for whatever reason wish to do this to yourself

Well, I fixed the problem. I raised the entire interior above the point of where the table would be. This also placed the other objects below the interior and into the void. Now it seems I have another issue. My frame rate is tanked. Now I can’t hardly move. How do I fix that?

EDIT:

The horrid frame rate was being caused by the default items continuously falling into the void. I fixed that by placing a collision barrier under the house. This acts as a net to catch everything. Believe it or not it worked. Now everything is working and looking perfect. Talk about a hokey fix… This has got to be it.
