LibreOffice Calc wants to open an ods file as a csv when another user has the file open

Have ods files an a SMB server share. If one user has a file open for editing and another user tries to open it Calc thinks it’s a csv file and pops up the csv option dialog box. It will not open the file no matter what I choose. I assume the default behavior is to open it as an ods file in read only mode but that does not happen. Both users are on the same version of Linux Mint Mate 21.0 and LO v 7.3.7.2. Same thing happens if the file is open for edit on a Linux machine and you try to open it on a Windows machine with the same version of LO.
