Deletion from database not possible

using influx with Openhab3.1. Trying to delete some entries where the values were wrong but facing an issue. Any ideas?

```
select * from Aussen_Boden_Feuchte where value <0.30

> name: Aussen_Boden_Feuchte
> time item value
> ---- ---- -----
> 1628079367121000000 Aussen_Boden_Feuchte 0.26

```

```
delete from Aussen_Boden_Feuchte where value < 0.30

No source file or test is identified. Start by reproducing the SELECT and DELETE statements from the report and tracing the reported field-predicate error. Before work is considered done, establish whether this deletion is intended to be supported and define the expected behavior or documentation for the result.
