It sounds like you are trying to adjust the margins in a PDF file, but when you increase the left column, the first column becomes too narrow. This can be frustrating, but there are a few things you can try to fix the issue.

1. First, try adjusting the margins on the entire document. This may help to redistribute the space and allow you to increase the left column without making the first column too narrow. To do this, go to the "Page Layout" tab in Microsoft Word and click on "Margins." From here, you can select a different margin size or choose "Custom Margins" to adjust the margins manually.
   
2. If adjusting the margins on the entire document doesn't work, you may need to adjust the column widths individually. To do this, go to the "Page Layout" tab and click on "Columns." From here, you can select "More Columns" to adjust the column width and spacing. You can also choose "Equal Column Width" to make all columns the same width.
   
3. Another option is to adjust the font size or spacing within the columns. If the text is too large or the spacing is too wide, it may be causing the columns to overlap or become too narrow. To adjust the font size, select the text and go to the "Home" tab. From here, you can choose a different font size or adjust the spacing between lines.
   
4. If none of these solutions work, you may need to consider using a different PDF editor or converter. Some programs may handle margins and columns differently, so it's worth trying a few different options to see if you can find one that works for your needs.
