OS initiated transfers?

Any ideas why my Icedrive dashboard (windows 10, app version 3.62) certainly seems to be doing a lot of transfers at the moment by itself; they are called ‘OS initiated transfer’. I try to cancel them but more appear?

Only thing I can think of is that the Windows Defender Virus scan I initiated caused this?

Update - A restart of the dashboard seems to have stopped the behaviour and it is back to uploading only files I add/delete to the synced folders.
