Clinical data tab: table gives no results after sorting on patient ID or Sample ID

[AnikaBongaarts]

In the "Clinical Data" tab from the study page (example https://www.cbioportal.org/study/clinicalData?id=gbm_columbia_2019) when clicking on "PatientID" or "SampleID" the table disapears.

when selecting other columns (for example mutation count) the table returns.
