I'm having issues with the antibarrel, where when several Reliquary items are in it and I attempt to take them out, they come as ghost items which will stay there on client side (this is single player...) until I attempt to move it or open a "server-side" inventory (i.e. anything other than the 'e' button), whereupon it vanishes.

The real ones stay in the antibarrel, which is noticeable as the tile becomes empty without sorting items into that slot (with only 1 in the stack) or the stack doesn't decrease.

Extracting them via an item transport system works fine and probably so would a mod which can directly access the inventory, though I haven't unlocked that stage yet

After testing various items from Reliquary these one do it:
Ender Staff (w/wo pearls)
Void Tear (w blocks, since it is stack-able otherwise)
Rending Gale (w feathers)
Harvest Rod (w bonemeal)

I haven't seen seen this happen to any other items or mod, any ideas?

Modern Skyblock 3 3.3.1.3
YABBA 1.1.2.5
Forge 14.23.3.2670

Is this still issue in latest Yabba? Reopen if it is
