Import from Another Catalog often loses Content-Aware Remove information

I have two Macs: Maci Mini and Macbook Pro both running MacOS 12.7.2 and Lightroom 13.2 (this also occured with Lightroom 12.

This is my regular editing scenario:

From my main Catalog on the Mac Mini, Export as Catalog a batch of photos (just the previews not the negative files) to a shared drive on Macbook Pro

Open the catalog  in Lightroom on Macbook Pro

Use the develop module Pro including Content-Aware remove on specific photos 

Export as Catalog the modified photos to a shared drive on the Mac Mini

Import from Another Catalog and select the catalog that was exported from Macbook Pro

After the import is complete, 0 to all the photos may not have the Content-Aware updates applied.  It seems quite random which photos are not updated correctly.  It seems worse the more photos there are in the catalog being imported.

Now, I can select all the photos and use Photo->Develop Settings->Update AI Settings whcih can take hours.

I can also go into Content-Aware Remove and there's an option there to update the settings - which might take 30 minute for each photo.

However, I have found that if I Import from Another Catalog again, select the same catalog, uncheck all the photos and then just select one photo that wasn't previously updated and import it, the updates are applied correctly.  So clearly, all the required information was in the catalog being imported but for some reason it skips some of that information when importing a lot of photos.
