Running 2 instances of FTL V6 - Versions not same

Hi,
I am running 2 Raspberry Pis, on two different networks.
Pi 1 is a Pi 4 and Pi 2 is a Pi 3B
To day Pi 1 say there is an update to FLT, but not Pi 2.
Checking their versions they are clearly different.
Some how the two branches are not same for FLT - how to correct this?
I must somehow have given a commend to change from development to fix.

Pi 1
admin@pihanlop:~ $ sudo pihole version

Version is v5.17.1-280-g9a3affd (Latest: null)
Branch is development-v6
Hash is 9a3affd8 (Latest: 9a3affd8)
Web
Version is v5.19-680-g1dcf90bd (Latest: null)
Branch is development-v6
Hash is 1dcf90bd (Latest: 1dcf90bd)
FTL
Version is vDev-04cf2e8 (Latest: null)
Branch is development-v6
Hash is 04cf2e83 (Latest: 04cf2e83)

Pi 2
admin@pihole2:~ $ pihole version
Core
Version is v5.17.1-274-g9a3affd8 (Latest: null)
Branch is development-v6
Hash is 9a3affd8 (Latest: 9a3affd8)
Web
Version is v5.19-653-g1dcf90bd (Latest: null)
Branch is development-v6

FTL
Version is vDev-4cbe8b4 (Latest: null)
Branch is fix/resolver

This command will change FTL branch to development-v6:

pihole checkout ftl development-v6

Hi rdwebdesign,
Thanks and have made a note on how to and FLT is now having the same version on both Pi Holes.
