Text Covered by tab bar at top of window

I’m very new to LibreOffice, so I apologize in advance if any of my issues have somewhat obvious solutions to someone very familiar with the application. I’m running macOS 10.13.3 on a 2014 iMac.
When I click on LibreOffice Preferences in Calc (I assume something similar or identical would happen if I were in Writer or Impress.), something like a tab bar opens at the top of the window that obscures some of the preference options text at the top of the left-hand side bar with the menu of the various settings available. I can only see a small sliver of the mostly-hidden text under the tab bar and can’t scroll the window contents to see what’s hidden. For example, if I choose “Memory” or “Paths” in the left side bar, there is text I can’t read that’s covered by that tab bar at the top of the LibreOffice window in both the left sidebar and also above the right hand window with additional choices. This seems like it might be a coding bug; maybe it isn’t seen on a Windows machine or even with another version of macOS. I’m running High Sierra on a Mac. How can I prevent this text from being covered by the tab bar at the top of the preferences windows?
Your help and suggestions would be appreciated.
