Arranger not working quite right

When I “flatten” a tune in the arranger track, the most recent versions of the tracks are not the ones that show up.

For example, If I’ve copied 4 beat measures into the drum track from elsewhere in the track, the newest ones do not show up, it’s the previous or original pieces.

I’m not sure if this is related, but I’m finding that when I copy a section of a track then paste it elsewhere, what gets pasted is not what I’ve copied, but some previous version of what was in the section which I copied.

Any help would be appreciated.
