Unknown File Type (smb client)

Thunar 1.8.14

Hello! After updating Xubuntu 18.04 LTS to 20.04 LTS, there was a problem with the association of .doc and .html files in a network folder (in the file properties the field type is "unknown"), if you specify in the .doc file properties in which program to open it (LibreOffice), then html files are also opened through LibreOffice. If the .doc and .html files are copied from a network folder to a local one, the file associations with the program work correctly.
