Synthesis Pack Size Idols Not Working?

Based on the pack size listed after entering a map, it seems that the pack size is not being properly increased with the corresponding Idols that say: ~"Synthesis monsters in synthesis maps have 20-25% increased pack size".

I think this is similar to when the atlas tree wasn't working on the unique maps? Maybe also being applied to idols.
Thanks and godspeed.

I tried 3 of them, can confirm no significant difference :(

tested the same, also tracked gold to be sure, the idols do nothing sadly
