Can't reinstall switch once delete in Switch port mapper

Can't reinstall switch once delete in Switch port mapper

Hello,
I changed a switch out for another model and rediscovered it. The old switch had 32 ports, this one has 12. Once I rediscovered it the 12 ports were right for the new switch, but still had 13-32 of the old switch as port of the mapping. I tried deleting the switch and re-adding it. But now it says that the switch already exists. I stoped and started the oputils and rebooted the server. What's next?

Also the export feature still give the summary.

Please let me know what now?
Thanks
