Maybe you are using "not reuse" option when
dealing with resource, and that might be problem
for deleting current line from resource - instead
it is deleting next resource line.
This is just a guess...
Is it possible to use async with is element exist? I'm trying to match an image in my browser but running 3 simultaneous checks with async but when I do, it seems like the async function never completes. Is it even possible to do this?
Thanks for your help
Main script: 
Function: 
An asynchronous function runs on a separate thread, unrelated to the thread from which it was launched.

It would be better to check three selectors in turn in one browser.
