Same problem
I had to rollback to the 7.7.7 version and delete and reapply the same filter I used before
Which is Category > equal to > category name > include
Did something happened with a value dropdown field? I couldn’t change category name until I deleted this filter and added it again
Уже пробовала, Хром
В других браузерах та же ситуация (и не только у одной меня)
