I've been getting mail messages from a model I had blocked, and was curious why. I went into my mail system and pulled up the blocked models and found that the "slider" was switched off for all of the models.
So I turned them back on, and once I clicked off of the page and returned, I noticed they were all off again. I do not see a save button or anything that should hold the slider in the on position, there just seems to be a bug that doesn't allow the blocks to stay in place. Please look into this and let me know once it is corrected so I can make sure the block is activated again. Quote
