Sub Account: Full access rights to Shared Forms

I have been given access and admin rights to forms from another users account (csm...), but on 2 of the 4 forms, I do not have an option to edit them (CSM - Employment Application Form, and CSM - Consent Release Form). The only options that show are "More", but not "Edit Form"

These were forms I originally created for my client and then transferred ownership to their account. They now want me to make further updates and provided admin rights, but they seem to only be available on newly created forms and not the forms that I transferred to them.

Whatever assistance you can provide would be appreciated. 

I am able to see the problem you have. Could you please ask the person who has the main account give you access by choosing 'Select from my forms' option as seen below?

It should solve the problem. Try it out, let us know if the problem still persists.
