grid events of the week. bug?

[JuanCar29]

If I create a new event from the week's grid, all the ones I had created disappear. But only on the first day of the week. If I leave after a month and come back a week they appear again, that is, it does not delete them but rather they stop being seen. If I create another event on another day, those from the first day disappear again. I have to go a month and come back a week to see them again.
I am with version 11 of Laravel.
