Steps to reproduce:

1. Go to advanced settings and tick "Use UI Automation in Excel spreadsheets) option
2. Open an Excel spreadsheet.
3. Enter text in a cell.
4. On the cell where you just entered text, press NVDA+shift+C to make it a column header.

Actual behavior:

When I press NVDA+shift+C or NVDA+shift+R to set automatic row or column header reading in Excel with UI automation enabled, I wind up in an edit box to edit the contents of the cell instead of creating row and column headers for automatic reading. Note that this is not at all a problem when UI automation support is disabled.

Expected behavior:

Pressing NVDA+shift+C or NVDA+shift+R should set automatic row and column header reading.
