Hello Bharath,
Sorry to hear that you ran into this issue.
It looks like you tried to attach a screenshot or a copy of your project file to this thread. Would you mind attaching them again so we can take a look?
Regarding the behavior your experiencing, one way to test if the issue is font specific is by using a standard font like Arial to isolate the behavior.
Additionally, if this is possible, try downloading the Kruthidev from a different source. There is always a chance that the font that you downloaded might have had some issues with it, and replacing it with a similar font from another source might help.
If the issue persists, open a case with our support team here so we can take a closer look at what's happening.
