Power meter usage: persistent data gap

Hey!

i have created a page similart to the demo temp page.

Now if have adapted the configuration to my needs, but the diagram is missing monday stats.

my used persistence service is influxdb2. the data for all mondays exist in the database.

here is my code from the page:
