8 icons are showing the the AQ index from 3 days ago till the forecast in 3 days. This number should be constant, even when an index for a specific day is missing. E.g. in the example screenshot "Binnen 2 dagen" is missing. Next to "Morgen" the "Binnen 3 dagen" icon is published. In this case a grey colored icon should be visual to indicate that that specific day is missing.
