How many template can I create on admin panel? Why my created all node configuration deleted when i move to another windows?

Why my created all node configuration deleted when i move to another windows? Is it related to number of template or error related with [TypeError, Cannot read property ‘getAllFiles’ of undefined]](https://github.com/botpress/botpress/issues/2919#)"?
or Launcher Unhandled Rejection [TypeError, Cannot read property ‘engine1’ of undefined]?
