having problems adding links in upfront?

Hi, im trying to edit an image in upfront to add an external link however it does not save it ? see screencast - https://monosnap.com/file/fZmocVkz9Ed3yvNrBzS4OQvAzQ1cvH

link that i want to embed
1) Colour CAD Plots to here - http://tinyurl.com/o95ebbf
2) Board Mounted prints to here - http://tinyurl.com/qcd234t

Support Access open till 18th (in both domains)

Note: two domains
1) http://tinyurl.com/plletgb - main domain (where images will be linking from) - trying to edit upfront here
2) http://tinyurl.com/ounlhnf - Shop domain where images will be linking too)

Thanks
