Stretched Logo Image (on parts of mobile site but not other)

Hello,

I appreciate the design of this app and it is going to look great, so thanks. I am having some trouble getting the center logo to stay consistent throughout the mobile experience however.

The header logo looks good on the homepage on mobile on an iPhone 7 but not Android, and both the iPhone 7 and Android are showing a stretched version of the logo when looked through the pages of the site.
I doubled the dimensions of the normal logo and it still is displaying it.

Any help would be greatly appreciated.
