Sorry, I presumed you upgraded the store from Ps 1.6 . (I just noticed that it's from Ps 1.7.5.2 upgraded and not too)
Upgrading the store from PS 1.7.5 to the latest 1.7 shouldn't have generated such issue. I don't have time right now, but on Monday morning once I'm in the office I could check - in case that is an option. Not getting a closer look, and from what you shared is almost impossible to figure out the issue.
Cheers,
Leo
