Zen Wifi XT8 - different FW on nodes

[Cheoah]

We've got 3 AIMesh nodes, works reliably, very few to no issues, even with 2.4-only IoT. I've rebooted only a handful of times over the last year, and only issues I can recall were ISP.

Updated a node today, and noticed they are running two different FW.

386_40577 on main router and one node, and the other node 386_45934.

Working fine, just curious if anyone knows why? They all show up to date FW after rebooting all.

My eyes are fading... The prefix is different too.

9.0.0.4.386_40577
3.0.0.4.386_45934

The one starting by 9 is beta firmware. You installed it manually once and have to manual install back to stock firmware if you want same version
