Unable to configure 1524 AP for MESH mode

[sirwallace66]

When I added to AP to the WLC i checked AP Mode Bridge.   I recieve the following error message  "Please change the 80211a channel and TxPower assignment method from GLOBAL to CUSTOMwireless->Access points->Radios->802.11a/n->Configure"    I am able to make the change on slot 1 but not slot 2.  I recieve the following message when I try to make these changes on slot 2.  "Error in setting Channel Number Configuration.  Error in setting TxPower Level Configuration"  I'm not sure what I'm doing wrong.

Having the same issue on 7.6.110.0.

AP's have previously been connected to controller in bridge mode, now cannot change from local to Bridge.

Slot 1 has been changed however slot 2 throws the error MSG.

These same AP's have been connected to a controller on 7.4 Code previously.

Looks to be an issue with the code, reverted back to older code and did not have the same issue.

Once the AP was converted to a Bridge in 7.2 I then upgraded the controller  to 7.6.110.0 and the AP's were configured in Bridge mode without the issue.
