I was able to fix the problem with the following custom css to overwrite the default css.

default css:

.datepicker.datepicker-inline td, .datepicker.datepicker-inline th, .datepicker.dropdown-menu td, .datepicker.dropdown-menu th {
  padding-top: 10px;
  padding-bottom: 10px;
  color: #ADB2BD;
  float: left;
  text-align: center; }

custome css:

.datepicker.datepicker-inline td, .datepicker.datepicker-inline th, .datepicker.dropdown-menu td, .datepicker.dropdown-menu th {
float: none;
}

Yes it was set to “Plain”.
I set it now to “Post name” and the ? disappeared.

Thanks, it’s working now!
