Language filter for Top Streams not filtering

[JerryCZZ]

There is 4 issues with same text but it's outdated or something else about filters so I write this with my problem.
After time maybe after updates plugin on FF the language filter stop work. I choose language "Czech" I will go to "Top Streams" tab and it's on default filter with all online streams. If I choose more than 2 language then filter automaticly reset to 0 filters. I tried relogin, reintalling plugin and tryed on Chrome (New fresh install) but also have same problem. In another language filter have same issue. But if I try search streams by some text like "Czech" so it will find some streams with this filter.

FF ver. : 74.0
TN ver. : 1.1.213
