Map selection and especially match options should reset when matchmaker leaves. Testing if match had had pro-options wouldn't been easy since it was 2 vs 2.

very strange,if someone of the room have pro and he got the host thats the reason that maitained i guess.

but anyway,it can be a lag,if the room get full and the match get started,it may reset to the normal sets and the castle map.

one question,do u play mobile too?

To answer this, it has occasionally happened to me in the past. The host left, or dc'd and rejoined the lobby (this one was me a couple times), and the settings were still showing the previous ones but reset after having gone a round.
I typically only play 2v or 3v, so I can say that even though it shows, it wouldn't have any pro options applied.

1 player joined to that match but apparently got scared about pro options and left.
