, 1st you should select a new CPU partner for one of your coached players, and then on the following week, change again for one of your players...
I should surely add the option to simply break the team...
I kept running into problems with one or the other player not being eligible to switch because they were either in a tournament that week (even though the tournament had ended) or were entered in one the next week.
I finally shut all four players down for the same three week period. Next, I started selecting new partners beginning with the one who had the best doubles ranking. It is a good thing I did, because she was able to select any of them, but as I moved down the list I discovered that the top ranker wasn't on the list for any of the other three, and none of the top three were on the list for poor Emily (who was bottom ranked).
So, Pauline chose Francine and immediately appeared on Francine's page as her partner, which is what should happen. Then Emilie chose Emily, but Emilie did NOT appear on Emily's page — Emily's old partner remained there. This worried me for awhile, but when the week changed the old partner dropped off Emmily's page and was replaced by Emilie, so it turned out right in the end.
Thank you for your help, Manutoo.
