Header / Footer Dialog Closes On Input of Character "O"

when I use the header and footer in the calc sheets I am unable to use the letter O without it closing the formatting screen nor can I type an R without it automatically highlighting the rest key. Am I needing to disable something?

In multiple different calc sheets when I try to type the letter O it closes the formatting screen and whenever you try to type an R it highlights the reset key. I am unable to us those letters in the header or footer. Neither capital nor lower case letters. I just installed this program last week on a new computer.

Edit[Opaque] Changed title and moved description into detailed section

I just installed this program

Which OS and LibreOffice-Version do you use?

Additional Info: The bug seems not to appear in 6.2.6.2, but in 6.3.0.4 - May be this is bug #tdf127219, though character “o” isn’t mentioned therein, but many others.

I have a HP, windows 10, newest version of libre. I am not techy sorry.

What does it mean I am not a techy sorry - that you are no longer interested in your own question?. Great. then please close it as outdated.

Pardon me, Opaque. It just means I am not very tech savvy and if I am not explaining something right that is why. I would very much so like to have this problem solved. Very frustrating to use and finding it glitchy with numerous letters. Thanks

Please understand - no technical information, no help possible. It is really that simple. And stating newest version isn’t a technical information but your own assumption of the version you have installed. Nobody here expects you to be able - from a technical perspective - to follow the bug I’ve mentioned in my comment. But without your cooperation nothing can be said or evaluated. So please go to Help -> About LibreOffice and paste all of the version information starting from Version to Calc: threaded (incl.).

Please enter a bug at Bugzilla.

Describe the error exactly and add a test file. Make all the important information like OS and LibreOffice version.
The link from the bug then please write here in your question. To do this, edit your question. Thank you.
