TEXNZE has large gap in 2007 data

import ddlpy

locations = ddlpy.locations()
bool_hoedanigheid = locations['Hoedanigheid.Code'].isin(['NAP'])
bool_stations = locations.index.isin(['TEXNZE'])
bool_grootheid = locations['Grootheid.Code'].isin(['WATHTE'])
bool_groepering = locations['Groepering.Code'].isin(['NVT'])
selected = locations.loc[bool_grootheid & bool_hoedanigheid & bool_groepering & bool_stations]

start_date = "2007-01-01"
end_date = "2008-01-01"

measurements = ddlpy.measurements(selected.iloc[0], start_date, end_date)
print(measurements[["Meetwaarde.Waarde_Numeriek"]].max())
measurements.plot(y='Meetwaarde.Waarde_Numeriek')

Is this to be expected or a mistake?

In #16 there was a more extensive overview of gaps provided, that can also be created for this station if necessary.
