New event width is wrong in Unit view

When I create a new event in Unit view, the event is rendered at half width.

If I drag the event to a new location, switch days and come back to it, or refresh the page then it appears in the correct, full width.

Do you have any ideas on how to fix this?

Thanks

Problem doesn’t occur locally.
If you still can reconstruct it - please provide any kind of sample or demo link where it can be checked.

I’ve sorted this out, wasn’t a problem with the scheduler after all
