Source text from mogrt PPro

Hello, gentlemen of the experts.
I am faced with the following problem. I import mogrt (via extendscript) into Premiere Pro. Import goes well and I can change all parameters except source text and color, I just can't see second parameter in the list and when I get mogrt text it displays some letter (not even English) as if it has strange encoding (although I tried UTF-8, UTF-16, Windows-1251), well. But when I try to change the text, it just erases, but nothing is written. Also, no errors either, as if it doesn't recognize my text.
However, this problem is ONLY when I use mogrt exported from PPro, with mogrt from AE there is no such problem. But here's the problem, I need to get the text from mogrt exactly from premiere pro, because that's the only way I can change the color of each word (in mogrt from AE I can only change the color of all the text).
