Bug in upgrading library (drupal)


When I try to upgrade old content instances to the newer library versions, the system keeps loading and doesn't upgrade a single instance. 

When I try to open an instance that's made with the old library, it doesn't appear anymore. This happens with 'course presentation' and 'single choice set'.

When I make a new instance it works perfectly with the new library.

Can somebody help me? Thanks in advance!
