Remove Value from input_number

Hello everyone,

I have an entitie input_number like shown below.

    name: Gas Meter Reading
    mode: box
    unit_of_measurement: m3
    min: 0
    max: 99999
    step: 1

With this input_number i also fill my utility:

  source: sensor.gas_verbrauch_qm
  cycle: daily

and monthly and so on. But unfortunately today I put in one digit too much. 11121,32qm instead of 1121,32. So my values are nor 10.000 to much. Is there any way to remove the value from the database?
Or purge everything starting today?

Some help would be great. Would be a shame if I miss the values.
