Changing betweed dictionary got app locked in "loading"

As i changed from Strong's dictionary to Swe1917Of the app shows the dictionary but is stuck on "loading". (showing the loading animation)
It also shut the app down.
When i restarted the app, and directly selected dictionary it shut down again.
When i restarted again, opened commentary before, that worked, bookmarks worked, but when i chose dictionary it remained in the "loading" state.
this time it did not shut the app down. It has now been loading as long as it have typed this message...
