Ammunation skill progress not saving

Ingame nick: Cameron
What happened?: After spending 10-15 minutes "sharpening" my ingame weapon skills in Ammunation, I left the game for a few hours. Upon returning, I discovered that all of my weapon skills are back to zero. (i was an on-duty police officer.)
This is the second time it has happened, the first I did not report. Not sure if other people have been experiencing it.
Date and Time: 26.3.2020 ~~19:00
Steps to reproduce the issue: Train Deagle and Micro SMG/Tec9 at Ammunation from 0 skill, as a Police Officer.

No screenshots, as I didn't screenshot my skills after training and there's no point in screenshotting my weapon skills. (which are currently zero.)

Thank you for reporting this issue to us, I will log this issue for you now.
