T5013 - Box 001 - "You must enter a valid partnership account number in box 001 of the T5013 slip" - Won't Accept Info From Slip

[TucDream]

For the 2021 tax year I cannot get the T5013 to accept the Partnership Account Number (823615257) that I have been using for years for this investment. 

Any ideas?

fwiw, the problem (finally) solved itself today, April 19th ... don't know why.

I tried yesterday clearing Box 001, but no luck.

Fired it up again this morning, retyped the number into Box 001, hit review, and no more Netfile warning.

I have uFile update on, so perhaps that is it?
