Libreoffice 4.4 doesn't look right in linuxmint Rebecca 17.1 after installing via ppa


I am using Liuxmint 17.1 and libreoffice used to look good when I had its original installation, but recently I installed libreoffice 5 through a ppa method I found here Install LibreOffice 5.0 In Ubuntu Or Linux Mint Via PPA ~ Web Upd8: Ubuntu / Linux blog , only to later find that there weren’t any compatible extensions with this version yet, so I uninstalled it and installed libreoffice 4.4 through this ppa deb trusty main. But now libreoffice doesn’t look good. The interface looks strange, especially when I run the “save as” dialogue. How can I return to the previous look?
