BF 7.1.2 bug (suspect hard-coded number in the code)

I have been testing a migration from BF3.8 to BF 7.1.2. But I hit a deadly problem today:

I have 1008 access groups in my BF 3.8 system, when I tried to create the access groups in BF 7.1.2 using a script, the script runs fine, all access groups got created in BF7.1.2. But when I open the GUI and go to Administration -> Access Groups -> click open any one access group, I got a blank in the "Owner" box.

If I delete a few access groups and reduced the total number to be 1001 or below, the owner box will show the correct name.

Also, this might be causing my earlier issue, where the import does not work properly, the environment variable groups did not get imported/created. (I am import a BF38 export file).

Please provide a fix or workaround, this is a show stopper.
