Problem when Indicator for Alt. labelling for functional location activated

Dear Experts,

In our test system, i had activated alternative labelling for functional lcation for an interface with Locations in ISU.

After i activated it the entire labelling for functional locations got changed to some arbitrary sustem generated number. For a sample -?0100000000000000142. Is there a ways i can retrieve the original names back. We have reactivated it to inactive again.

Please help.

Thanks,

Boby Mathew
