7.5 - Chromium mode [Error - An item with the same key has already been added]

[Neel1]

while i was working on chromium mode in v 7.5, i noticed that in Dynamic wait - Two different element are added and while running i am getting error - An item with the same key has already been added.

When i use either of one - then no error is coming.

Yes. that's the problem statement.
