Fortiap 221C wrong Region Mismatch, how to change?

Hello all, 

i have here 2 AP's @my home with an Fortigate 60E. So in Fortigate Interface i see the message "Health poor - Country/Region Mismatch" on one of this two AP's. I live in Austria an one of the AP's would not get this Countrycode. So it stays on "no Countrycode" (A) @the AP's Cli. So i'am able to change this?

And the second question, is this required? Because they working normally. So it looks likes only an beauty mistake...

If i separate the 2 ap's with 2 different ap profiles, the one with US did not work here in Austria anymore.

Very Thanks and best Regards :)
