[Arabic] These combinations appear wrongly

[AlsoScratch]

The character ز in each of these combinations incorrectly appears in its final form

Please elaborate on your post before we can take a look into this.

What is wrong in your opinion? What would be right?
Under what conditions (OS / application) does this occur?
What version of the font are you using?
Did you try alternative solutions?

Version is IBMPlexSansArabic-Regular.ttf Version 1.004

Is this a hypothetical character combination? Or are there words that actually use this?
What does your input string look like?
What environment do you use the font in?

Again: please elaborate as much as possible.

The characters are U+0632, U+062C, , U+0632, U+0686, , U+0632, U+062D, , U+0632, U+062E.
It happens when I use the font on web pages through my Google Chrome browser.

Thx. I identified the culprit in the font’s features. The error appears in the opposite situation too, where the final form is swapped for the default.

Will be fixed in an upcoming update.
