Playing ATM9, 0.2.46, Forge.

Have an Advanced Compacting Upgrade in a barrel; it will not compact any combs from Productive Bees. In match item mode, the combs cannot even bee added to the list. The same happens with match mod mode. Though, I did try to put a different item from the mod in the list to no avail. In match tags mode, even after adding both of the combs tags (forge:honeycombs, itemfilter:check_nbt), still nothing. I have also tried the regular Compacting Upgrade. I have tried all combinations of the various options.

Regular honeycombs with compact just fine.

That would be because they use nbt to differentiate between the combs so this would require support for compacting items with nbt. I will lave this here as enhancement and think about whether I want to support that.

Thanks for checking it out. I did find out the Simple Compacting Drawer from Functional Storage supports this, but I would much rather use Sophisticated Storage.
