It looks like the door with missing symbols is
A water and filled circle
We have the pattern tag.
Looking from the top right symbol, we have a hint:
I interpret this as "Backwards correct"
Looking from the leftmost door (X and square) and the symbols in the top, we can see
Something's common: the square in the symbols and the door.
The next door has a symbol of filled circle and broken outlined circlea sun-like symbol. Seeing this and the top one again,
The broken outlined circlesun-like symbol is common.
Continuing,
The airport symbol is common in the right door and the symbols. This means our next pattern will be a water symbol.
What about the cross and the filled circle?
That's obvious: Cross in left, filled in left, cross in right, and our next pattern should be filled in right.
Yet I don't know how will the cipher tag will work for this one.
