Libreoffice issues after upgrading from F36 to F37


Recently I have upgraded my system from F36 to F37, and one important glitch really prevent to do my work further. It seems somehow Libreoffice writer installation is broken during upgrade because as the writer launches, it seems to work fine, loads my files correctly – but basically all the drop-down menus has lost the capability to pop their submenus if they have that arrow in the list. I tried to reinstall, but seems something remains because the error remained till now. How can I solve this to reset LO Writer settings to default, or know that not packaging has missing module elements? Did someone meet with this problem? TIA

I have tried many options, what is included complete reset from the Help menu, and within that all other options, but no use…
