Select by Category/Manufacturer

[ZZZZZeeeennn]

My shop has no longer have an option to select by Category as I choose a Manufacturer listing, nor does it have an option for "Select by Manufacturer" as I choose Category. I had this option before.

I don't know what made it disappear. I've done three things and those are as follows:
1.) I used Easy Populate 1.2.5.4 to add 200 items. I've done this numerous times without a problem.
2.) I deleted 90 items from my shop using CPanel's phpMyAdmin database system. As I got back on my ZenCart Admin, it told me to delete some debris left over or that nature so I did. I never deleted items using CPanel before.
3.) I upgraded my ZenCart from 1.3.6 to 1.3.7.

Under Admin's Product Listing, "Display Category/Manufacturer Filter" is set to 1.

NEED HELP!
