Submit Feature doesn’t works, also some other bugs

Hello, plugin looks nice with it’s functions but it doesn’t works !
1)Submit Feature button doesn’t works, I can’t see it from PC, from mobile I can see it but sometimes pop-up window doesn’t open, or if it opens only half up side is viable on smartphone, so you can’t even click submit button.
2)If I choose a group it says new feature requests is closed for this group but I haven’t actually closed from admin panel.
3)Also I have enabled comments from admin panel but in front-end it says comments are off
4)Also it always says you have 0 vote remaining, so I can’t vote.
I had to uninstall it, please solve all bugs
