Bug-report Plugin Simple Calendar Version 3.1.14

I found a bug in your Free-Plugin:
In Calender-view of an event, which goes over more days, it shows on each day a different end-date of the event!
That’s very ugly and resolves in misunderstandings and trouble.
Please refer to my website under: https://www.kempo-studio.de/terminkalender/
If you call the event “Geschlossen!”- beginning on the 26th of march (and ending on the 6th of April), it shows you in the hoover-view of the 6th April: ending on the 11th April. This is wrong!
