Organ formatting is non-standard
Usually, organ literature is formatted in one of two ways:
1. Three staves, the top two (the hands) of which have a bar line going through and are bracketed, the third of which is no bracketed, nor does the bar line go through to it.
2. If the pedal part is simple, then it will sometimes be written into the second staff of the score, and there will be no third staff.
I propose that #1 be default.
Currently, neither of these are default. There is an attempt at #1, but whoever decided that the bracket and the barline should go through all three staves got it wrong.
An easy workaround is to double click the bottom of the bracket, grab the blue handle and bring it to the bottom of the second staff; do likewise with the bar line.
