Cannot reorganize mod priority

[Jason33w]

I'm in the process of finishing up my S.T.E.P. installation but all of the sudden, I can no longer reorganize the load priority of my mods in the left panel.  Is there a button I accidentally pressed?  THanks in advance for any help!!

Maybe you've clicked on the bar that lists all the columns, and by doing so you're set it to order mods by something else than priority?

If so, just click on the Priority column header in that bar (quick screenshot to explain what I'm referring to)
