Most blocks conflicting with the Furniture mod from same author [1.16.5]

Whenever I place something down, like a fuel drum, or fluid extractor, it just appears like a waterlogged gate or mailbox. It also happens with the furniture mod. I tried reinstalling both of them and still the problem goes on. Here is my mods folder.

I investigated a bit more and it's not just the vehicle mod, it's ALL mods that have blocks. I installed the CustomNPCs mod and the mailboxes... are cabinets from the furniture mod. Also, this is being done on a Aternos server with Forge modloader.

Actually, it's not the vehicle mod, it's the furniture mod. I'm going to try and reinstall it.
