I used to send files through the Bluetooth icon that is located in the context menu when I right click the file I want to send.

Recently, if I want to send files through Bluetooth, I discovered that it is no longer there again. I have tried to fix it, but no solutions yet.
All I see is .btwsendto kind of folder that does not show the Bluetooth icon again.
