Problem with levels

[fading sand]

Already I completed R5A1 and it does not show as completed. And on R4 I completed 50% levels, same problem

[graceful beacon]

There is a graphical bug that occurs as follows

You join someone else's lobby, hosting a mission in Rundown X
Host swaps the mission to any other Rundown (which we shall call Rundown Y)
The completion numbers on your rundown screen will reflect the number of clears you have for Rundown X, although you are looking at the screen for Rundown Y

An example of this would be you join someone hosting a Rundown 1 level, and then they swap the mission to one in Rundown 2
Your rundown screen will only reflect the clear numbers in Rundown 1, so it'll show that B3, B4, D2, and E1 are uncleared, even if you have completed all of Rundown 2

this bug could be to blame here, though you'd need to remember/confirm if you were in a lobby as client when host swapped rundowns (I can see that there is the lobby button on the first screenshot)

This bug you mention gets fixed by just quitting the lobby and opening a different rundown

I know it because it's super common to get it if you use ingame matchmaker
