Yealink Endpoint Manager does not clear Fields

Using the Endpoint manager for Yealink and configuring a SIP-T46U..

Endpoint manager version is 15.0.41.49 but above option what not available to select it.

Line Button was programed as Conference, then changed to BLF for extension number.

When changing the Line Button back to "Conference" the Label does change to say Conference however the button still performs the previously configured action.

Connected to the wep portal on the phone and noted that the Value field still had the extension number in it and the Label field had not cleared either.

Manually clearing the fields in the phones web portal corrected the issue and the phone then performed the correct action.

It appears that if a function that does not require a value entry then the fields are not cleared even though you did clear them in the endpoint manager config screen.
