This is a glowstone slab from Consistency+ (which I may add works great with your mod)
However the name display in WTHIT is showing Full Slab rather than the correct name tag.
Not really a huge issue, but strange nonetheless as some do display correctly like this 1, right next to the one above.
ps..
not an issue with Consistency+ tags, as when not used in conjunction with another slab it displays the correct name
Yeah, it's something that happens when slabs are mixed because that creates a different type of block, might need to look into more direct WTHIT compatibility
See screenshot
