Known Bugs

I noticed that Im getting 4 fields from the Apps Builder and while using them in Task Magic some of the columns are not being map correctly I dont know why this was working before 100% sure. You can see in the image that the column names dont match correctly dont know why. Looks like the problem is the name I used but it should not affect in my opinion. First name was LinkedIn_Article and second cas LinkedIn_Article_URL looks like it was ignoring the _URL and using it as text instead of the name of the variable. Whats the best way to name my variables?
