Issue replaying FIT file on a Mac with 4.1.1

With SDK 4.1.1 when I try to replay a FIT file, by:

1) Select Simulation > Activity Data from menu

2) Change the Data Source from "Data Simulation" to "Workout FIT file"

3) Choose a FIT file (I have several that I use for testing and I know what the data looks like)

4) Press the "Play" button

5) Press the start button to start the timer

It is not actually replaying my FIT file, but is actually simulating data - what is shown on the screen in no way matches my FIT file (which I can verify by rolling back the SDK to 4.0.10)

I wonder whether step 2, above, is actually having any effect and it's always stuck on "Data Simulation".

Anyone Else experiencing this?

Environment:
