Canvas text's font problem

Hi to all,
I have a canvas with 3 texts(or 4 but it doesn’t matter), the problem is that sometimes the texts appear strange like you can see in the the image… Why?
I use one font that i have downloaded, sometimes it works perfectly, sometimes it doesn’t work, and i want to know why :frowning:
Ps: the problem is only with the canvas, with the Gui text the font works perfectly!
Thanks for the help!

Please delete your all texts and add new text with new font
