Question about heist

Hello.

I was doing a blueprint mission and went into the first "bunker" (out of four) and didn't find anything useful so I left without taking any of the items in the final room (I triggered the alarm on my way out, but lock down didn't start yet).
I left the place through the portal to store the items, like I always do, but this time the portal was closed with all the other 3 "bunkers" unexplored.

Is this normal? Is it a penalty for not grabbing an item from the final room? Or what could I have done wrong this time?

Thanks in advance.

Fixed a bug where remaining portals could disappear for players when returning back to some areas.

Ah, I see.

Thank you.
