The first thing to remember is that repeats are a print function. Your song must perform correctly in a linear form before getting the fake sheet to work. So all the hints that the forum has given you are correct.

Now think how this song might look in fake sheet mode. The first return is easy, and so is the second, but how to get the chart to show a complete repeat takes some thought. You really can't put another repeat followin section'B'. The best idea would be a DS, either al coda or al fine.

The DS would be at the end of section B, the sign would be at bar 1, the start of section A.
