There is no Virtual Appliance (VA) created at cluster or host level.
You have no VA working at cluster or host level but the job(s) are configured to run using the Auto transport option or the Hot Add radio button is selected (as well as the LAN transport option) under Custom Transport.
In this case the 2760 ... HOT ADD transport unavailable is acting as a warning, stating that there is no chance to run the backup using such transport option and you will get a double arrow icon on those tasks.
In order to avoid those errors on the tasks, as well as getting a small performance improvement, you should remove the Automatic transport selection, select Custom Transport then select On this vRanger Machine and leave only the LAN transport selected, as shown on the image below.
