Can you please attach your project and the hex file generated so that we can try to program at our end and try to recreate the issue?
Also, you can refer to the efuse_gen example project provided with the PDL. You can find this in the installation directory and by default, the example project would be located in the following directory - C:\Program Files (x86)\Cypress\PDL\3.1.2\security\secure_image\examples\psoc_creator\efuse_gen.cydsn
Hope this helps,
Thanks and Regards,
