When working in InDesign v 14.0.3 x64 on my PC, I've encountered a new problem when trying to align text in a bulleted list using the "tab" key.

After keying in the text in my list, I create alignment by first inserting tabs using the Type > Tabs command, and then using the "Tab" key on my keyboard to align second and third lines of text. Lately, when I move my cursor down to the second line of text and attempt to use the tab key to align the text with the tab I set in the line above, InDesign inserts the numeral "1" on the line (see attached screenshot, where I've marked the numeral with a red circle).

No matter what I try, I cannot get it to stop inserting the numeral 1 in the line. I've even tried re-setting the tab, to no avail. I've saved the file, closed all applications, re-started my computer and attempted to update InDesign via Creative Cloud, but nothing solves the problem.

The only option I have to align items in my bulleted list is to insert a soft break (Shift + Enter) and use the space bar to move the line of copy to the right incrementally. Unfortunately, this does not offer perfect alignment.

Can you please help?
