Broken thresholds (colors doesnt apply in the correct way)

We are experiencing a weird error when working with Grafana 7.0.4 (and even in 7.1). In a table on our dashboard we use the override functionality on our columns to apply: thresholds -> value mappings -> cell display mode: color background. The colors arent applied correctly. As a datasource we use elasticsearch.

Here is the weird thing.
When opening the dashboard the colors are not loaded correctly. After going into the edit mode of the table and just clicking on color of the threshold and reselect it again - its applied correctly for this specific column. But when saving the changes again and reloading the whole dashboard its broken again.

Looks very unstable tbh.

Here is a screenshot of the setup (some values are excluded to keep it small):
