I moved mid year, including home office. I use simple method

I moved mid-year, including my home office, and i use simple method for deduction.  One office I lived at 5 months, the other 7.  Why is the business conducted in home limited to 100%?  Say home office 1 i work at 60% of the time when living at that house (40% visiting clients).  Say home office 2 same thing.  I work 60 % of time when living at that house.  TT wants the total time working at the different homes to be less than 100%.  What is wrong here?

 

funny thing is that TT is calculating the correct home office deduction, but it is giving me errors.
