In Word, a black dot in front of a heading is usually because the heading has some kind of list style or paragraph marker applied to it. To get rid of these black spots, here are a few things you can try:
Method 1: Modify the style to remove the black dots.
Place the mouse cursor over the title with a black dot.
In the menu bar of Word, click on the "Start" tab.
In the Styles area of the Home tab, locate the style applied to the current title (for example, Heading 1) and right-click it.
In the menu that pops up, select the "Modify" option.
In the Modify Style dialog box, click the Format button in the lower left corner.
In the menu that pops up, select the "Paragraph" option.
In the Paragraph dialog box, switch to the Line Breaks and Pagination tab.
Uncheck the same page as the next paragraph and No pagination in the paragraph.
Click the "OK" button to close all dialog boxes.
In this way, the black dot in front of the title should disappear.
Method 2: Remove the black dots by canceling the paragraph marker.
Open the Word document and display the paragraph markers. This can be done by clicking the "Start" tab in the Word menu bar and then clicking the "Show Hidden Paragraph Markers" button in the "Paragraphs" area. If the button appears as a symbol like , the paragraph marker is already displayed.
Find the title with the black dot and select it.
In the menu bar of Word, click on the "Start" tab, and then click on the "Bullets" button (usually as a small dot or other symbol) in the "Paragraphs" area.
In the menu that pops up, select the "None" option to unbullet the title.
This way, the black dot in front of the title will also be removed.
Please note that the above methods may vary slightly depending on the Word version or specific settings. If the above methods can't get rid of the black spots, you can try checking other settings of the document or searching for a solution for a specific version of Word.
