XT8 backhaul with RC5300

[Kape1234]

So the problem is, I have XT8 and RC5300. Both set as aimesh nodes.

RC5300 is wired to main router (AX 11000). XT8 doesn't want to connect to to RC5300 using 5GHz backhaul. It only connects using 2.4 GHz, even when in the same room. Or to AX11000 using 5GHz.

If I take another RC5300 and use it as aimesh, it does connect to first RC5300 using 5GHz.

If I put RC5300 as aimesh main router, XT8 DOES connect to it using 5GHz.

Also, RC5300 (aimesh node) DOES connect to XT8 (aimesh node) using 5GHZ in aimesh.

What's the catch and is the a fix?

Latest firmware on all.

It seems disabling Smart Connect fixes the problem. Is there an option to be tweaked, so I wouldn't need to disable it completely?

AX 11000 doesn't connect to RC5300 with 5ghz backhaul also. Only when smart connect is disabled.
