Firmware version MISMATCH alarm after upgrade Firepower 2110 to version 6.6.1

Hi,

I just recently upgraded two (H/A pair) Firepower 2110 from version 6.2.3 to 6.6.1

The upgrade went well. However, I noticed the following alarm message when the upgrade was done

Hardware Alarms - Firmware version MISMATCH. Contact Cisco TAC for assistance.

When checking the firmware version from FXOS with the "show system firmware expand detail" command, I noticed that there is some differences,

One of the appliance is showing

Firmware-Vers: 1006.0104.0213
Rommon-Vers: 1.0.06
Fpga-Vers: 1.4.00
Fpga-Golden-Vers: 0.0.0
Power-Sequencer-Vers: 2.13
Firmware-Status: OK

and the other is showing:

Firmware-Vers: 1010.0200.0213
Rommon-Vers: 1.0.10
Fpga-Vers: 2.0.00
Fpga-Golden-Vers: 2.0.00
Power-Sequencer-Vers: 2.13
Firmware-Status: upgrade successful

So the firmware versions are different, but I don't think that I can upgrade the firmware manually. If I understand it right, the firmware should be included when installing FTD package.

TAC found a bug - https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvw34538
that seams to match this issue, but it's a bit unclear if it's just a cosmetic bug or something I should worry about?.

Anyone else experienced this?

This seems to be cosmetic issues as it has no business impact.
