Mx 5.10 company expenses shows error message when changing between My Expenses and Company Expenses

I downloaded the 5.10 beta company expenses project and deployed to the sandbox. Steps to reproduce: Run the desktop version. Use the manager account Choose Company Expenses. There is one expense of the employee account pending Choose My Expenses again. Error 'An error occured, please contact your system administrator.' Browser console log is empty, no errors in application log. I tried our production app with the beta. When opening the first page and after sign in (transfer from anonymous to real user) I get this error too.
