Yoast SEO fails to mark some URL's as fixed

I’m using Yoast SEO 3.0.7 and have 12 rather long URL’s in the search console which I can’t mark as fixed. A typical URL is:

/tools/popup-image.html?name=/activities/images/stgregory/dscf0027.jpg&title=Interior%20of%20St.%20Gregory’s%20Church&from_page=%2Factivities%2Fstgregory.html&from_name=St%20Gregory’s%20Church

This produces the following error message in my Firefox error console:

Timestamp: 04/01/2016 18:25:54
Error: SyntaxError: missing ) after argument list
Source File: javascript:wpseo_mark_as_fixed(‘%2Ftools%2Fpopup-image.html%3Fname%3D%2Factivities%2Fimages%2Fstgregory%2F060114-p1141530.jpg%26title%3DInterior%2520of%2520St.%2520Gregory%27s%2520Church%26from_page%3D%252Factivities%252Fstgregory.html%26from_name%3DSt%2520Gregory%27s%2520Church’);

After marking all other URL’s as fixed the “wpseo-gsc-issues-web-not_found” record in wp_options contains just these 12 URL’s. Would there be any adverse side effects if I were to remove them, either by deleting the record or replacing its contents with an empty string?
