HREAP mode AP assigns random 5GHz (802.11a) channel after reboot

The channel and power levels for the 2.4GHz and 5GHz radios have been manually configured on an HREAP mode AP. The 5GHz channel is 149 (non-DFS) with a power level of 2 (14dB). When the HREAP mode AP reboots the 5GHz channel initially displayed is the same manually configured 5GHz channel. If the AP is unable to connect to the WLC and enters HREAP standalone mode, the 5GHz radio channel is then randomly assigned a channel from the UNII-1, UNII-2 or UNII-3 bands. The WLC is on v7.0.116.0. I have seen the same results using 1142, 1262, 3502i and 3502e APs. See example CLI output from AP below.

Any thoughts as to why or how to prevent?
