Does the Onkyo HT-R590 have Dolby Pro Logic IIx?

I was scrolling through the listening modes by pressing the Movie/TV button. The modes I was able to get included: TV Logic, All Ch Stereo, Full Mono, T-D, Direct, Mono, and Multichannel. There's no Dolby Pro Logic IIx to be found. Does it exist for this model? It's listed in the user manual but I can't find it anywhere. Am I missing something here?

I have my system set up in a 7.1 configuration. I noticed that the two back speakers had no sound coming from them when I watched movies. I searched for solutions online and found one solution was to turn the mode to Dolby Pro Logic IIx. But as I mentioned, I haven't been able to find that option. Any suggestions? Thanks.
