Word Placed a 1. in forn ton the horizontal line above footnotes

[gxs0lvi]

Hello,

I have a document that I have been working on for a while. It has many footnotes. I started out normal and now in front of the horizontal line above the footnotes put a 1.

like this

1. _______________

54 Ibid., para 300.

I tried all I know and chatted with MS help for 2 hours today. They finally reloaded the program and gave up. I start a new document and it is fine. I cut and paste to a new document and the issue remains.

The pull down for footnote and endnote show a custom mark of 1. I can erase this but it will not let me apply.

Windows 10 and MS 365.
Thanks in advance.
