TDV-bar-card now provides a narrow view

The TDV-bar-card has suddenly gone weird on me. It was not working on a cube view for swipe-card (it disappeared). So I deleted it and inserted a new card on the dashboard. Cut/pasted the list of entities in but now it appears all narrow as per picture

The code looks like this:

type: custom:tdv-bar-card
title: Energy Consumption
rangemax: 2000
entities:
  - entity: sensor.fridge_plug_current_consumption
    name: Fridge
    icon: mdi:fridge
  - entity: sensor.washer_current_consumption
    name: Washer
    icon: mdi:washing-machine

Does anyone have any suggestions on how I rescue this card.
Help is much appreciated.
