Grid Multiple sort icon 1 missing

     We have a grid that has a multiple sort on it. Icon 1 and the arrow is missing, while we can see icon 2 and the arrow. If we click on the first sort it changes to 3 with an arrow. 

Our sort descriptor is as follows:

const [sorter, setSorter] = React.useState<SortDescriptor[]>([
        { field: "orgDisplay", dir: "asc" },
        { field: "userKey", dir: "asc" }
    ]);

and we have: 

sortable={{ mode: "multiple" }}

to allow multiple sort on the grid.

Is there something that would prevent the 1 and the arrow icon from showing?

Thanks
