Jobs & Experts Upload Attachment Not Working

Greetings,

Previously I had an issue regarding Avatar Upload that has been addressed ( https://premium.wpmudev.org/forums/topic/jobs-experts-not-uploading-avatar )
However, I have the exact same issue with the Uploading of an Attachment, the Choose File button does not trigger. How can I fix this issue? Do note, this happens with Subscribers' login and not so much with Admin login.

Also, when will the next Jobs & Experts update be released with some of the previous fixes?

Thank you.
