iReal pro has 16 spaces in each system (line)
Usually divided into 4, 4-space measures (bars)
Some chart are written with 8, 2-space measures (bars)

By adding or removing spaces in the editor it is possible to convert one type of chart to the other. It may be easier to write a NEW chart displayed as you wish.

Always edit a DUPLICATE. That way you will not loose or mess up the original.
