WBS renumbered on every open

[Sean of the PMO]

We are storing Microsoft Project schedules in a Project and Portfolio
Management tool (not MSPS, alas). Every time the schedule is opened from
within the tool, the WBS field is wiped out. If the "Generate WBS code for
new task" checkbox is set, every task gets a new and different code from what
it had before. If that checkbox is clear, the WBS field is completely erased.

Any idea why this might be occuring?

Have you tried contacting support for the tool you are using? Doesn't sound
like an MSP issue as the problem is happening in your other unnamed tool.
