Ranking problem in SWAT - Can't rank up?

I am having an issue with my rank for SWAT not increasing. I seem to have hit a wall and it will no longer increase. I got up to Onyx rank 1830, and even with further wins would no longer increase. With losses my rank will go down, but even after further victories I will no longer go up. Not sure if there is a bug there or what is going on. Every other playlist appears to work normally and I’ll rank up and down according to wins and losses. Even this past weekends Shotty Snipers playlist worked just fine.

I’ll continue to monitor it as I don’t play SWAT very often, just thought it odd that my rank would no longer go up as my friends I’m playing with continue to increase and even pass me.

Any help or input would be greatly appreciated.

Thanks
