TOPIC: [SOLVED] Registration Form Calendar Pop-Up CSS?

I'm trying to find where the css for the pop-up calendar within the registration forms is.

With the latest upgrade the pop-up calendars in my forms, where registrants choose their birth date, is showing up without a background colour, and because this pop-up calendar shows above the fields below it, the visual is very busy and hard to read.

Any help on finding where this can be adjusted and/or how I can add a background to the pop-up calendar would be much appreciated.

Here's another screen shot of the calendar, it's pretty much un-useable. I've tried searching through the boards here for the answer but haven't had any luck. Anyone out there that can help?

Updated to Joomla 3.7.1 and the calendar is working again

Interesting. We had found this issue and fixed it within DT Register and included it in the next update which we are trying to wrap up. Joomla... sigh... always making us change stuff!
