Hello,
Thank you for contacting us and reporting about problems.
But we just looked on our demo and don’t see any of the mentioned. You can check here http://demo.xtemos.com/basel/
Of course, any software products have bugs so it is not a problem. If you report something we will fix it ASAP. We release our updates every two weeks (see changelog).
Also, we see that font size is set to 18px on your screenshots. Probably, you have changed it in Theme Settings -> Typography. Please check this and write us about the result.
Kind Regards
Xtemos
