Steps to Reproduce: 1. sign in, go to mobile redirects 2. create new redirect 3. add condition, and then add property 4. type e.g. "touch.enabled Equals true", save changes 5. edit properties again by replacing old value with "screen.width Less than 240.00" 6. after saving changes there is: screen.width Equals 'true' Less than 240.00
Similar behavior is with user agent strings - when you delete already existing conditions (not by trash icon, just leave blank condition by backspace), after saving changes they are not deleted.
Fixed the problem with properties. Regarding other issue, it doesn't seem an issue. If the user agent string is to be deleted it should be through the trash icon.. otherwise, a blank value, which is not acceptable, will be restored to previous value (if any).
