WP Manager (Form Labels Are transparent?)

First of all, this plug in is fantastic! It does exactly what I need it to do, and more.

I’m just scratching my head about this minor thing about the forms – I noticed that the form labels are either white, or transparent. I cannot see them for some odd reason. You can see what I mean by going to https://baqerservices.com/post-a-job/

Any thought on how to change this would be greatly appreciated.
