Upgrade button not showing

Hi all my fine fellows … been quiet apologies… having a wee bit of a problem here on a now live site…

Told clients they can upgrade to a Bronze sub level, and lo and behold it shows that they can do this in their subscription page… but there is button !!!!

At first i thought yea yea.. so i tried myself …. and yep button is utterly utterly gone… and it was there b4, that i am sure of, as i took screenshots of it…
