Mass Effect 1 - Paragon not working

hello possibly helpful people!

so, im on my fourth play through of the ME series, and am having some problems with my Paragon. i will provide as many details as possible without being too overwhelming in case the details explain what's going on.

after my femShep was made a Spectre, i went to Eletania in the Attican Beta to use the Paragon bug (done with the space monkeys that stole the dada module) so i could have the Paragon i needed but could still do some Renegade options. i like my characters to be well rounded 🙂

after doing filling up my Paragon, i went and got Liara from Therum, and have since defeated the geth near-invasion in the Armstrong Nebula. i then went to the Kepler Verge, to Ontarom, to do the mission where former Alliance (and now Cerberus) scientists are being killed by Coporal Toombs because of their part in the Akuze tragedy. i have full Paragon now, so i expected id be able to do the Paragon speaking option during the ending.

nope. 

i just dealt with Rear Admiral Mikhailovich (that's a spelling adventure!) and his inspection of the Normandy, and there was no Paragon option again. this is really frustrating since ive never had this issue before, ive restarted the game and the system and went back to the save, to talk with him again and once again, no Paragon options. 

should i start this round over? will Paragon start working at some point? was the Paragon bug patched or something to stop the points from being effective? any helpful tips would be greatly appreciated. 

a few more details in case it helps, im on a PS3 purchased in 2012, this copy of ME1 was bought through the PS store and ive had minimal to no problems with it since buying it, and ive done the Paragon bug every time ive played it and there have been no glitches like this.
