The JPG screen capture is "nice", but not what I would hope for when asking for a "sample doc". My definition of a sample doc is just that a DOC, or DOCX or DOCM (etc), that contains example text that demonstrates the issue. If you can't recreate the issue
by copy and pasting into a new blank file, you can make a copy of the problem file and then deleting most of the text to leave just the problem area. And at the same time you would remove any sensitive/private information in the example.
The reason I would ask for a sample file is to try possible fixes to find the "right" one, aka one that actually works on the sample.
The reason you have those unrecognized styles is that word will create required styles in your document when copy and paste from other documents that use styles you don't have. The simplest fix for that problem is to use Paste Special and select "Text Only"
so that the new text will use the style in the current paragraph (usually that will be the "Normal" style). This way you avoid creating these random new styles.
But, since you already have they styles, you can get rid of them by using the style pane to select all examples of the offending style then applying one of your own styles to all of the selected text.
Since you mention docx, I'll guess you are using one of the ribbon versions. So the general steps you would follow are:
- In the Home tab > Styles group, click on the Styles "dialog launcher button" (the little icon on the extreme right end of the Styles group name bar). This displays the Styles Pane
- Right click on an Offending style
- Select "Select all"
- (after several seconds (or minutes <grin>) word will eventually "select" all occurrences of the offending style
- then locate and click on a desired style in the Styles pane to apply that style to all occurrences
- Right click on the offending style
- Select "delete style"
- repeat until all offending styles are fixed.
