Bar hidden behind another bar

I’m fighting this issue for a few days, where 1 bar gets hidden if I have more then 2 query’s. As soon as 1 disable 1 query the other bar is shown again. Is this a bug or am I doing something wrong.

Grafana v7.0.5 (efbcbb838b). I have tested with the same data in a MariaDB and InfluxDB, both give the same result.

Query options ‘Min interval’ is set to 1d.

My InfluxDB query’s:

A

SELECT last("value") FROM "DailyPowerProductionUsedTotal" WHERE $timeFilter GROUP BY time(1d) fill(null)

B

SELECT last("value") FROM "DailyPowerUsageTotal" WHERE $timeFilter GROUP BY time(1d) fill(null)

C

SELECT last("value") FROM "DailyPowerProductionTotal" WHERE $timeFilter GROUP BY time($__interval) fill(null)

All query’s enabled:

When you look closely, you see the orange bar with a few % visibility when you hover the mouse over the bar.

Query B disabled:

Who can help me?
