Polylang and Learnpress

I have installed polylang and made my site bilingual (English and Arabic). However, I use learnpress for my courses information. Learnpress does not show the option to choose language. I have used arabic webfonts to make the arabic text well readable. However, learnpress goes into the arabic (right to left text format and some characters such as + . etc) come in the wrong places. Also, for the learnpress pages(i.e. courses) the menu displays the arabic one.
Please tell me the way to solve this.
