Missing Emblem of Triumph

Just wanted to write here and know if someone else experienced something similar to my issue:

I had 17 Emblems of Triumph when I checked yesterday, I'm not sure if I did PoS before or after checking the quantity of EoT, let's say it was after I've done PoS.

I ran Trials of Champion HC after that I checked my EoT quantity and it's 16...O.o

GM's can't help with this issue... So I wanted to share with the community to know if someone else experienced that?
