Project 50 stems a mess!
Project 50 has plot sub tree and plot sub sap as "1", if at all, meaning 100% probably (impossible numbers for 1 sq. m). Need to check this project carefully, as there is also a thrice duplicated big stem: once as module 0, size 1, once as modude 1, size 1 and once as size 133 (correct).
The SAS tables don't have data in them, so it's not clear to be how these data were added to the archive database.
