I then tested Ubuntu Budgie and was unable to reproduce the error.
Also tested Kubuntu Groovy 20.10 and no error opening Samba files.
So far this has then only occurred on Lubuntu and Xubuntu.
Again I will reiterate that this only occurs with LibreOffice documents on the Samba share - all other applications used to open file i,e featherpad,mousepad open as normal and use the same password to access the share.
As a follow up I tested another machine running Xubuntu Hirsute and again received the "Document in use" error .
