Ive noticed yesterday when using my friends tithis andromo (dunno if its written right) banker, that the categories repeat themselves, like i was scrolling and my items repeated themselves twice before reaching the end, something like that:

Daggers
-Alkosh dagger
-NMG dagger
Materials
-a
-b
-c
...
...
...
Daggers (Once again, same items)
-Alkosh dagger
-NMG dagger
Materials
-a
-b
-c

I dont know if this can lead to item bugging, duping or whatever, i just found it weird and avoided moving them, also i didnt check if normal banker is working fine, just the andromo.

Its worth noticing im not a ESO plus subber, so no double inventory for me.
