Bug 128403

Description:
Observed using file with conditional formatting applied based on date in Column A.  The date should appear in a date format, but sometimes displays as a financial format.  This is not consistently displayed, and can change if the display of the cells is refreshed by scrolling off/on screen, or by a file save.
I also observe that the incorrect financial format seems to 'stick' to cells with a thick lower border defined on them.  Should be visible in attached spreadsheet, which was created by copy/pasting ing a small section of my personal accounts spreadsheet into a new file and removing all data except dates.
  The conditional format setup may be ambiguous as its is applied across multiple columns with date, test and number (financial) entries.

Steps to Reproduce:
1.Apply formatting combination to new spreadsheet
2.Open and / or save and dates are reformatted as financial numbers
3.Displayed format changes on refresh of screen (scroll on and off screen and displayed format changes
4. On save, some formats displayed change
5. Cells with border formatting seem to 'stick' at the financial format


Actual Results:
Copy existing format to new spreadsheet.  Dates shown in column display inconsistently, and can change when refeshed by scrolling them on and off screen.

Expected Results:
All entries in column A display as a Date format (e.g. Fri 2 Aug 19)


Reproducible: Sometimes
