Repeat not working when nested inside D.C. al Coda

I'm currently working on a piece that is organized as ABA', i.e. part A has a bit different ending the second time. Thus I wrote the piece as follows: A1 (To Coda) A2 B (D.C. al Coda) (Coda) A2'. Thereby parts A1 and B contain ordinary repeats within them. Unfortunately, this inner repeat of A1 doesn't get executed when A1 is played for the second time in the "outer D.C. loop"; instead it directly takes the 2nd volta part. How can I get MuseScore to repeat the "inner loop" as well?
