Updater not ignoring files

[oakling]

I'm using the updater but am having a problem with the exclude setting (I'm currently using a different tradeskill window).
I go into ignored, find the file and double click and the line turns red, I click okay and get the message 'please go to settings and check the files you want the updater to ignore' I go back into ignore and find the line I had checked to be reset.
And it does overwrite the file if I click update.
