Font colors displaying incorrectly

I have had difficulties with the most recent version of Libre Office I am running Windows 10 x64The latest problem is that it does not allow me to choose font colours on my spreadsheets. Any numerical figures default to blue and text defaults to black. If I open up the Format Cells (Ctrl + 1) it shows the color I have chosen but not on the spreadsheet itself.
