purge not working correctly with redis database

[osevan]

debian sid
wordpress latest master
php stack latest stable from php.net

i have setupped everything and 2 years before everything worked with red button purge entire cache..

10.10.20.56:6379> keys *

1. "mydomain.com_page:httpsGETip.x.x.x/--mobile"
2. "mydomain.com_page:httpsGETmail.mydomain.com/--desktop"
3. "mydomain.com_page:httpsGETip.X.X.X/--desktop"
4. "mydomain.com_page:httpsGETmail.mydomain.com/--mobile"
5. "mydomain.com_page:httpsGETwww.mydomain.com/--desktop

even when i click on purge entire cache or purge cache above on dashboard

i uploaded picture with prefix field "mydomaoin.com_page:" i tried both "mydomain.com_page"

saved changes and purge button not working
my host field is of same like above my redis server

additional notes: dotes in field enable purge arent visible anymore, i can click and see if off or not , because menu options closes when i click, - it reacts but no dot inside Enable Purge field

thanks and

best regards
