Any styles using autonumbering are prone to corruption in some way. I haven't seen an issue with blacked out numbering but have seen differences in indentation, font issues etc.

The first point of repairing a doc that goes bad is to firstly verify that the paragraph formatting has no local formatting overriding the paragraph style settings. Do this by selecting and pressing Ctrl-Space and Ctrl-Q.

If the numbering is still bad, refresh the styles from the template.

If the numbering is still bad, run a macro to reset the autonumbering.

The macro is easily created by putting your cursor in a top level outline numbered paragraph, starting a macro recording and going to Home > Multilevel List > Define New Multilevel list. Once you dismiss this dialog you can stop recording the macro and examine what you have got. It will produce masses of code which can be cleaned up in a variety of ways but if you don't care, just stay with what it records.
