My cedilla is not generated together with the letter

Hi guys,

I am not sure if I am experiencing a bug, but here is the situation: I recently did a cedilla for the first time. However, when I exported for testing (both export and test install), the cedilla is going together with the letter, even when I copied the accent mark to place it there (as showed in the image). It also happens to the comma below accent.
So I am pretty confused about the situation and hope someone can explain if I did something wrong.
Thank you!

P/s: it works absolutely fine in preview panel.

What do you mean by “going together with the letter”?

Can you post a screenshot of what you see that is wrong, and explain how and where you test?

And are you circumventing font cache problems? Read this please:
