missing column header data validation list?

[asharkin]

Getting run time error and it looks like the column headers data validation list in Attributes worksheet is missing?

Same here without an runtime error! After syncing my project, I only see an empty filterlist.

Data Validation is showing the right source with the indirect formula but no dropdown menu is available.

I have the same Issue here. No error message and an empty filter list in Excel - just like the screen shot above.

Excel Version: Excel 2016 (no cloud version)

Edit:

That might be a Problem with Excel: If you just click at the small arrow it happens what is shown in the screenshot above. But if you click at the cell and not the arrow, a second arrow appears.

If that "new" arrow is clicked, the types appear.

It might be useful to add that to the documentation or the readme.md.
