I understand that you are placing a tag on script "Number of caches with word in the title" and require a "minVisitDate".
The script does not recognize this so you best contact the script writer.
I noticed that your tagging some difficult challenges and the config has no statement on the condition of the words
like > "whole_word": true <
For instand the word "run" will give a lot of caches which don't qualify.
On GC3VMC9 you find the same problem.
In any case I started using the comment box for placing a warning note for the future users who are going to check if they qualify for the challenge.
