Hi I am trying to put a report in ascending order in lightning mode and this error appears. 

Uncaught TypeError: Cannot read property 'firstChild' of null throws at https://mapbox.lightning.force.com/jslibrary/1562615648000/ui-analytics-reporting/LightningReportDep.js:100:178664

But if i switch to classic mode and click to put my reports in ascending order, no error. Please advise. I dont want to have to switch to classic every time I reorder the list, thanks :)
