Here is a screen of a completed task that I had to manually go into the database and alter the proximity table to finish.

Here is another screen where I try to put in any kind of number (I've tried editing with just a solid number and also the .00000 at the end of it and all I get is an "UPDATE ERROR" in the north-right corner and it does not save.

I also can't get my task to work. I've tried changing the coordinates to make a bubble proximity and nothing is working. It seems the proximity for other standard EQ tasks is working fine when I tested them. I don't know what I am missing here.
