You have a good practice schedule Bob and this really is about repetition so keep to your schedule. 

When I started I was very regimented in that I gave each exercise so many minutes per day. I have since changed this to a number of repetitions, usually 10. When something is totally new I go as slow as I need to in order to get clean chords. This can take time. We have to build dexterity. 

Something else to consider is the placement of the elbow in getting our fingers straight. I dug up an old video I made years ago for another member who was struggling with fingers and posted the link below. Hopefully you find it useful. Guitar takes time and repetition. 

Things will come together
