Arabic diacritics high above letters.

Hello, I seem to be having a problem with Arabic diacritics when typing in Illustrator.

The diacritics on some of my letters have risen above the letters and I don't know why.

The text in Illustrator looks like this:  

As seen here, the diacritics are way too high than normal.

But here's what stumped me, the exact same text I used in Illustrator in the program "Wordpad" is presented properly:

This (^) is how I want it to be, this is perfect for me. But in Illustrator this does not seem to work.

I really don't understand, I tried some other fonts with the same text, Adobe Arabic works, and other default fonts do as well, but fonts I installed don't work while some fonts I installed do work.

I've never had this problem before and I don't know what's causing it.

The font I am using is "al-Qalam Quran Majeed 1" and is available here: http://quran.mursil.com/Web-Print-Publishing-Quran-Text-Graphics-Fonts-and-Downloads/fonts-optimized-for-quran

Thanks in advance.
