Problems using "Export MLB Rosters" and "Import MLB Rosters" in a new league created by a "template"

One of my potential solutions for the issue reported in the thread "Persistent Underdevelopment and Extreme Development Risk in Long-Running Imported League" is to perform a "Soft Reset" of the league. The idea was to take and build a template of our league structures and start a new league from that template. Then using the "Export MLB Rosters" from the League Functions menu of our existing files, we were going to get the list of all players on all teams and start adjusting ratings outside of the game of the players who have missed out on 4 or 5 seasons worth of development, then use the "Import MLB Rosters" function on that new league to bring them in.
In testing, however, the export seems to work fine, with most if not all players shown under the MLB and minor league rosters accurately. When Importing them into the new league, even without editing the file at all, only a few players import and most of them are improperly linked.

Has anyone been able to get this to work (in this manner, outside of the main league files) before? Is there anything obvious that I am missing. My assumption is that there is a mismatch on the player ids which is causing the issue on the new files.

NOTE: The reason we aren't doing this in the same rosterset/files of our existing league is that all new players generated by the game are generating with little to no development chance at all. In OOTP25, we see that 5* international free agents and 5* draftees barely develop enough to get out of Rookie ball before retiring. In OOTP26, nearly all of our created players (over 90%) are being generated with "Extreme" player development risk values.

I could use any support here, including what things others have tried that didn't work for them.
