Apparently, you cannot edit a SalesForce profile template; you have to make a copy of it, which creates a custom profile (with a check marked), then you can modify the newly created custom profile.
I had installed a "managed released" package for limited test and deployment in a test Org for "Admin" only. I later wanted to deploy it to other profiles. When I could not include grant other profiles "full access", I installed the same version of the package again in the same Org, this time providing "full access" to "Standard User". But the objects that were developed in the Dev Org, and included in the released package, still show up as unchecked for each of R/C/E/D, for the profile's "custom object permission". As the Admin, I am unable to edit by clicking "Edit".

I just learn that due to a new 2010 frame release, we cannot edit certain profile. We can only edit a Custom Profile.
