SMB share cant see all files

This issue exists on several Macs at our facility.

We have a network share created using SMB. We are able to connect to the remote server just fine.

The issue is we can only see up to 25 files in Finder, regardless of how many files are on the remote server.

The remote server we are connecting to is an IBM iSeries (AS/400).

Is there a fix we can apply to allow us to see all files on the share?

Thanks!
