Clear cell changed metadata in OOO Calc

Question

I am trying to figure out how to clear the red highlighting around cells in Calc (OpenOffice 4).

Here is an example:

It is not affecting my work but I would like to clear them as they are distracting. I have tried searching but all I can come up with is to clear everything in the cell which does not work.

Just disable recording changes. Recording changes is a feature to keep some "metadata" about edits concerning your spreadsheet. It allows you to track some data about which changes were applied to the sheet, so a third person may review and acccept/reject the changes. When recording is enabled, every cell that was changed since is highlighted by a thin red border, and a popup informs about recent changed.

You can control recording of changed using Menu "Edit" -> "Changes". There, you will find also a feature to disable recording of changes: disable "Record". You will be asked for confirmation, but if you're not interested in the data recorded, you can safely confirm. "Data recorded" means the info in the popup box - date, time and content of edits regarding the specific cell, not the data in the cell itself.
