Yes it says 1 x 64 x 2. There is a left repeat at 1a and a right repeat with "x2" at 64.

To insert the blank bars I clicked on bar 1 and right clicked and selected Insert Bars (32). This inserted blank bars, then I typed in the chords on them.

When I put it in notation mode and run through it, the notation for 1-32 is correctly blank, and then the notes are there for 33-64, then when it repeats, it has the notes on bars 1-32.
