Inconsistent display of text size in Zoho TeamInbox

Inconsistent display of text size in Zoho TeamInbox

Font size in the Zoho TeamInbox user interface is not displayed in the correct size but a couple of points larger.

And when the email gets delivered the size of the message text is different from the signature text despite being set the same size.

I have set Vedana 12pt as Default Font for composing in Settings:

And I have also used Vedana 12pt as the font for creating signatures:

When I compose an email text of the message and text of the signature look the same size however they are both larger, more like an 18pt instead of 12pt:

But when the email gets delivered the sizes of message text is significantly smaller than the signature:
