Row id: 20 has been changed since last read. failure

Hi, I got this error, could you explain what is wrong? "Your Submission to the Digital Mammography challenge, docker.synapse.org/syn7228096/preproc@sha256:b3c6b7fe13cbbf5324f83edd13cf0f1e0e9e5bf18c8bcb86d0e09eaf84f24252, has stopped before completion. The message is: Row id: 20 has been changed since last read. Please get the latest value for this row and then attempt to update it again." Thanks Dezso
