Hierarchy Variance Table – right hand column vanishing

Hi – I’m using the hierarchy variance table and the right hand column continually disappears out of the right hand side of the visualisation box, even though there is plenty of room for the table to fit within the area.  It does this both in desktop and on the app service.

If I resize the box, the column returns to its correct position until I open a hierarchy level and then it vanishes again outside of the box.

This makes the visualisation unusable
