Logic mangles imported GB drum tracks

Two distinct issues with drum tracks (live recorded audio) imported from Garage Band to an existing Logic project. Or maybe they are connected and I don't know how.

1. sound quality changes (for the worse)
2. an unwelcome "groove" feel is applied.

I'm linking to the two clips in question as Logic projects. Links allow download from Google Drive.*

'right' is the project assembled in this order:

1. create instrumental project in Logic Pro, using "Drummer" track.
2. open the GB drums project in Logic, essentially converting it to a new & separate Logic Pro project
3. into the GB drums (now Logic) project, paste the instrumental tracks from original instrumental Logic Pro project.

'wrong' is is the project assembled in a different order:

1. create instrumental project in Logic Pro, using "Drummer" track.
2. open the GB drums project in Logic, essentially converting it to a new & separate Logic Pro project
3. into the original instrumental Logic Pro project, paste the tracks from the GB drums (now Logic) project

on the "wrong" version: I don't have any kind of Quantize applied to the drums. (There is some Q applied to a muted MIDI keyboard track.)

I think (it was weeks ago) that I applied a drum replacement filter on the snare drum after import. Can I get back to the original?

*I wish I could figure out how to make these Logic projects a bit smaller (tried Clean Up, tried Consolidate), as they are each only 4 measures long... but hopefully 300+ MB isn't prohibitive.

Much gratitude to anyone who can help me sort this!
