Citrix/Epic Selector Issue, validate but fails on run

So I am trying to do a datascape on table in epic, Scraping works when making, i am able to see all the data in a table format, selctor is green and validated both “attach browser” and “Extract Structured Data ‘TABLE’”

But as soon i run the flow or do a test activity , I get selector error "

Attach Browser ‘FileDProg Page’: Cannot find the UI element corresponding to this selector:

Why is this happening ? Even after fail, when i try to check selector its still valid and highlight works

I have so many epic navigation and click that works, so its not the run time or extension issue, its only failing here.
