Error when creating a new Tape

[Alerosso]

Hello,

When I try to add a new Tape in IRRICAD DATA BASE I receive the following error message (screenshot attached):

"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to allow duplicate entries and try again.

IRRICAD version 20.07
Operating system: Windows 10, 64-bit

Thank you very much for your help.

Best regards,
Alejandro
