Drop menu does not appear on windows 10

I have installed Version: on Windows 10 laptop. I am not able to see the drop down menu and icons are large. When I hover the cursor on the icon in second row, it shows the tip of the first row. E.g. when I click on printer icon, it shows the drop down for text, spacing, align, list … Then when I click the icon in the row below, it show the tip for printer.

When I open the libre office in safe mode, it works perfectly fine. Libre office does not seems to work correctly on windows 10. Please help.
