The reputation link is broken. A slash is missing. How to fix?

670 viewsIssuesrepuation page reputation

Hi, I just installed the plugin on my website. When I view my profile, a number show up next to my username, it is supposed to be linked to reputations tab, but a slash is missing, so getting a 404 error. Please tell how to fix it?
Shows up as:
mysite/questions/profile/adminreputations/ instead of mysite/questions/profile/admin/reputations/
My permalink structure is custom:

It works fine, if I change permalinks to /%postname%/ but I can’t do that cos my site is very old, will lose traffic.
