Trouble setting 16F1939 to 32mhz with intosc. (PLL X4 not working)

Hello.
This is my config:

It should run on 32mhz (8mhz clock * 4x PLL). However, it runs on 8mhz. If I set it to 16mhz, it works fine on 16mhz. So I guess, somehow, PLL setting is ignored. What I'm doing wrong?

I tried to play with PLL registers, but no luck...

If PLLEN in Configuration Words = 1, SPLLEN bit is ignored. 4x PLL is always enabled (subject to oscillator requirements)

why are selecting Timer1 oscillator for fosc ? its incapable of 32mhz operation or pll

Thanks!
Yes it was my error - set OSCCON=%11110000 and now it seems to be working correctly.
