New Version installing on Prod even though I select Sandbox

I’m trying to install the new version of SKUID but even though I choose sandbox, it shows that it’s installing on prod. Any help would be appreciated. I sent an email to SKUID but have not heard back in a couple of days.

Hi Marlen, Just to verify, are you logged into the Salesforce org you want to install Skuid prior to clicking the install button? Thanks, Matt
