Solve double installation of LibreOffice

I have L.O. 7.3 but yesterday, after an update of Ubuntu 16, I got another installation on top of it, L.O. 7.5.
On 7.3 I have some features, especially on Writer, such as zotero plugin and auto-correction items.
Is it possible to merge the two so that I can upgrade to 7.5 keeping the customization already done to 7.3?
Thank you
