Trialmaster fights not updating Challenges

This is my second timein a row going the distant with trialmaster in a T-16 map. First time I thought I did something wrong. Second time im submitting bug report. The only confirmation I have is the trialmaster says in his speech I won twice in a row. I Looked at Unbelievable Undertaking it says (0/3), Pretty sure T-16 map Plateau is a level 81 or higher. Thanks for looking into this report.
