Notification Panel Getting dragged while clicking on the last element of the page

I am storing all the element of a page in a list then clicking on them one by one from 1st to last and then scolling down the page and storing the element in new list and so on till the end of the app. page.
But when i am clicking the last element of the list then SOMETIME notification panel is getting dragged (not complete panel getting dragged) and click operation not getting performed.
I have tried TouchAction tap options.

I have tried after enabling “show pointer location” from developer options and i can see its not clicking last element and notification panel getting dragged
Please help…
