Quark's "Stripped X Wood" are tagged as #forge:stripped_logs, even though they aren't logs. To clarify, a stripped wood block is different from stripped log block in that they have the same texture on all sides.

In order to fix this bug, make sure that quark:stripped_blossom_wood, quark:stripped_ancient_wood, and quark:stripped_azalea_wood are NOT tagged as #forge:stripped_logs.

My version of Quark is 4.0-458, my Forge version is 47.2.0, and my game version is 1.20.1

Interesting, it looks like the forge:stripped_logs tag is completely nonstandard in the first place (it doesn't exist in NeoForge both pre- and post-tag refactor). Forge doesn't actually add any tag with this name. So the vanilla stripped logs in this screenshot are also being added by some mod, I think.

Vanilla used to have a stripped_logs tag, but only for a short time in the 1.19.3 snapshot cycle.

So maybe the correct solution would be to remove this tag entirely.
