Data Merge ignores files when a header field is called 'table'
If Data Merge tries to select a data source where one of its header fields is called 'table' (all lowercase), it fails to import (InDesign v 13.0.1). It doesn't seem to matter which column it's in, but changing it to anything else (e.g. 'Table' with uppercase 'T') seems to fix it.
Tried it on 2 machines, same result. Adobe Customer Care on Twitter confirmed they could replicate it and suggested I post it here.
Short video attached illustrating the issue.
Thanks for reporting the issue. We are able to reproduce the bug.
Just been trying to figure this out for two hours. I'm emotionally drained, but thank you.
