I'm having a problem with my custom selector.
I have an action to extract the element text and title from a list of elements. It produces the following table.

Then there is a loop to click on the first element (I will add more actions to perform before clicking the next item in the list.)

This is the static selector which I created by just selecting the first element in the list.

I modified it by replacing the title and text from my list of elements.

When I use the static UI element, the first element is clicked. But when I try to use the modified element I get this error, although the text of the selector seems to match the static selector identically. Any ideas what is going on here?

Thank you in advance.
