@Anaisdg Thank you for the reply. The behavior actually changed a little after updating to influx 1.7.9:
Now the query works as long as I only query data after the incident. As soon as I start a query that includes data from before the accident only the old data can be read. I pinpointed the actual time it happened and this is the data directly around the incident:
> SELECT * FROM "temperature" WHERE time > 1572036412756096000 and time < 1572037373055757000
name: temperature
time location location_1 value

So as soon as a query for “location” contains data from both periods the data stored in “location_1” is not returned anymore. When querying only before or after this timeframe everything now (after the update) works as expected. I would still like to fix this though if somehow possible because grafana is not able to display long time queries correct anymore.
