Those are error-checking flags.
Doesn't necessarily mean you have an error, but perhaps the data or formula in
those cells do not match adjacent cells.
Or you could have a number formatted as text.
ToolsOptionsError Checking will show the various resons for flags when
error-checking is enabled.
You can disable it or some of the options.
