Session Property (Host) not found

I note that sometimes when I login to my designer The host property in the perspective session property is missing, due to which when I run the perspective pages in the browser there is an error stating "session props host " not found. Whereas when I close and re-open the designer again I found the property present in the session props.
Is this any kind of glitch or any configuration to be done to get rid of this error.
Note: Gateway version: 8.1.20
Designer: 1.1.20
I've attached the snapshots of the sessions props before and after reopening for reference.
