Only 2 profile accepted in GPRS settings

Hi! I had 2 profile for GPRS on my M8: Mobile Internet and MMS. When i put another SIM in my phone, with another service provider i tried to set up a new profile in GPRS for this new provider. Everything was OK and i wrote Name, APN, etc and i pushed Save. After that i went back to Settings and yet the new profile didn't appear! It seems that Meizu doesn't know more than 2 gprs profiles. Then i thought to verify in UsrConnectNode.ini and there were only 2 profiles. I edited and typed data for new profile that weren't allowed me to enter previous in GPRS Settings.
[Internet]
IsSelect=0
APN=...
USER NAME=...
....
, in the same structure as i saw for the other 2 profile that were working. After that i saved the file and surprise: in gprs settings were 3 profile now and in addition,..they even worked. So if you need more than 2 profile for GPRS connection proceed as i did and it will work.
Good luck!

I forgot to mention that i have 0.9.2.7 fw.
