I keep getting a message to review my 1095a forms because "Your calculations could not be completed" Has anyone else encountered this problem?

I had coverage all year but changed plans during the year so I received two 1095a forms.  I was able to enter the months I had coverage and leave the months I was covered by the other plan blank and get through that section but when I went to review my federal return it told me to check the calculations in my 1095a forms.
