Hi Skye, You're exactly right, the expected result is as you described:
If you create a layout template report in the NWE, it will come in under
report type UITMPL and will report only NWE layout templates. If you
create a layout template report in Classic, it will come in under report
type LYTMP, and will report only Classic layout templates. I'm sorry to
hear that there was a miscommunication on this and happy to answer any
further questions. Thanks,
