regex filter doesn't work?

[lgasp]

I have subway tooter installed (version 5.545-noFcm), an I use it wi 2 mastodon accounts on 2 different servers.

Al the preset filters work fine (,like the "don't show boosts" etc) but the regex filter dors not have any effect as far as I could see.

Whatever I write, mi posts are excluded.

As an example, let's say I want to see all the posts that contain the word "ciao"; I tried to input both "ciao" or "/ciao/" (without quotes) but the posts shown are always the same, even if they dont contain the word "ciao"

Is the regex filter intended to work in a different way? I couldn't find any example or instruction to use it
