Any thoughts as to why my general tab would disappear?

 

No idea why the general would disappear, it should be at the top unless you have scrolled to the bottom of the filter list.
I would suggest to unselect all those filters that you don't use there by having a smaller list.
Do that by right-clicking over the filters and selecting the configure option and untick the filters you don't use 

Well, that got it back... but weird that it disappeared like that. When I went to the config tab it was still checked.
Thank you.
