Warning in log with default export to Excel function in DataGrid StudioPro 9.12.2

2
In version 9.12.2 I see a warning in the console when using the default export to Excel function (button) on a Datagrid. We moved from 9.6.9 to 9.12.2 with our app so I thought this might be an upgrade error.  But when I start a new blank app in 9.12.2 with just a simple entity, a DataGrid with an Excel export button I get the same warning when I click the button: org.apache.poi.POIDocument → DocumentSummaryInformation property set came back as null org.apache.poi.POIDocument → SummaryInformation property set came back as null Screenshot Anybody else noticed these warnings and found a solution?
