FTM/Ancestry - Edit Criteria scripting problem

This is best explained with a concrete example:

1. Select an ancestor from the List of Individuals: Mary Ann Pinnell
2. Go to family page
3. Click Web Search Resources button.
4. FTM searches and displays 1-50 of 947 hits

Most seem irrelevant. All the first few pages I viewed were priority
***, yet were mainly NOT 'Mary Ann Pinnell'. I'd say most are 'Mary
Pinnell'. To eliminate all but 'Mary Ann Pinnell', I assumed that I
could now use the Edit Criteria button?

But there seems to be some sort of bug.

If I click Edit Criteria, it changes to 'Reset Criteria' and the Name
column heading 'Mary Ann Pinnell' is highlighted. Not sure what I'm
meant to do now. But if I do nothing but simply click the Search
button, top right, I get the following error message:

waste of time

the database ahs got bigger over theyears and generates many irrelevant hits

best ignored unless very unusalnames
