Highend 2.1 upgrade resized Teser Box Images

Running Highend theme with ‘Our Services’ template page (since upgrade it’s been renamed to Client 3)
Issue since the upgrade to 2.1 & 2.1.1 is that the Teaser Box images are all now all different sizes.
I’ve uploaded & assigned different images and get different pic size results. In frontend
editor everything views perfectly uniform no matter what picture i assign though backend & actually viewing site on different browsers displays a mismatch of image sizes.
This is also the same for the ‘about us’ page portrait face images.
Both above pages were following the original template with only
personal content amendments.

Thanks for any assistance
