What I did:
I exported text as Rich Text and as PDF as well.
Notes in pdf were exported in right order, but Rich Text in inverse order.
I have also restarted App and changed sorting in the project couple of times.
What I expected:
Exporting in right order
Things that might be helpful to know (Agenda version, OS and model, etc):
Agenda version 6.0
MacOS Mojave 10.14.5
Actually I must always export in Rich Text and than copy all in Word to make adjustments, because unfortunately export in pdf function makes unaproppriate spaces.
