Update job info -> Blank profile (bug with last update)

Hello!,
There is a big problem when you update something in the Job tab, it makes the changes of the compensation/job info, but then it leaves everything else in blank (first name, last name, etc).
For what i understand, it might be leaving everything in blank when its the data from personal, but keeps the data from work.
I thought i was doing something wrong, but i just checked in a fresh localhost install and same problem.
Hope you guys can fix this asap or at least realease some hotfix in the meantime.

I tried it with 4.6 and 4.9 WP version, no other plugin installed and default theme. The language was in English.

*I posted this on the WP support section aswell and also sent an email, just to be sure that you guys can see this asap. No need to answer in each of them ofc.
