Tasalio, Cleansing Water resist calculation bug

Bug report reference number: 1.271.660.172.

I have the Chieftain mastery Tasalio, Cleaning Water allocated, which should convert 50% of my fire resistance to cold and lightning res. When I equipp a ring with +16% fire and lightning resistance and +9% fire resistance, the resulting resistances are not as expected.
Should:
Fire: 132 (107 + 25)
Cold: 99 (87 + 25/2)
Lightning: 82 (54 + 16 + 25/2)

Is:
Fire: 132
Cold: 99
Lightning: 74 (8% resistance is missing)

I tried unequipping, chaninging zones, changing other items. The bug stays conssitently. In Path of Building, the resistances are calculated correctly as expected with 82% lightning resistance. Here are two pictures of the ring in question with the stats.

The issue is with PoB, not in-game. Hybrid stats are counted differently than explicit fire resistance, so they don't apply. PoB is still incorrectly assuming it works separately and GGG does not support PoB.

Bug report in PoB:

So the hybrid stat only counts towards cold resistant for Tasalio but not to lightning resistance? That seems weirdly inconsistent, but looking deeper into it, it seems that GGG is not able to implement it properly due to how it is coded. (hybrid mods already effect the resistance at 100% of their value and they cannot effect the same resistance again for 50% of the value because one mod cannot effect the same stat twice).

Thank you for the clarification.
