duplicate id in sms_cv api call

When querying data from https://sms-cv.helmholtz.cloud/sms/cv/api/v1/measuredquantities, id 46 is returned both on

the end of https://sms-cv.helmholtz.cloud/sms/cv/api/v1/measuredquantities/?page%5Bnumber%5D=1 and the beginning of https://sms-cv.helmholtz.cloud/sms/cv/api/v1/measuredquantities/?page%5Bnumber%5D=2

This creates an error (see comment below), when trying to insert it into the database.
