Is it a problem on my end, the resource pack, the integration mod, Dynamic Trees mod?
Thanks

Maybe if I used F3 before opening the issue i could have noticed that those blocks are from compat mods : dtbyg and dtbop

EDIT
Context: I'm making a 1.19.2 modpack so I was interested in BYG and DTBYG foliage.
I fixed my problems, there wasn't a dtbyg folder and dtbop was missing an entry (maybe more but I have to check).
