yellow diamonds

[SimonDavies]

Hi there, Using the home licence of ArcGIS (ver 10.7.1) I've published two service definitions from MXDs , then published the service definitions to tiles and added them to a new web map in AGOL. I can see all the layers there for both services in the web map, but they have yellow diamonds at the front of the layer instead of  an empty box with the ability to tick the layer visibility on. The yellow diamonds are also blocking the ability to turn a layer on in the web app.

Would appreciate your help... S
