rtl problem

Hi
My first time with All-in-One Event Calendar and It’s great.
I’m having some trouble with the rtl in single event.
I tryed addind this code to my child theme, but it didn’t have any influence apart for the color.
Here’s my code:

.timely {
    color: #fafafa;
}
@media (min-width: 768px)
.ai1ec-col-sm-push-7 {
    right: 58.333333333333% !important;
}
@media (min-width: 768px)
.ai1ec-col-sm-1, .ai1ec-col-sm-2, .ai1ec-col-sm-3, .ai1ec-col-sm-4, .ai1ec-col-sm-5, .ai1ec-col-sm-6, .ai1ec-col-sm-7, .ai1ec-col-sm-8, .ai1ec-col-sm-9, .ai1ec-col-sm-10, .ai1ec-col-sm-11, .ai1ec-col-sm-12 {
    float: right !important;
}
@media (min-width: 768px)
.ai1ec-col-sm-pull-5 {
    left: 41.666666666667% !important;
}
@media (min-width: 992px)
.ai1ec-col-md-1, .ai1ec-col-md-2, .ai1ec-col-md-3, .ai1ec-col-md-4, .ai1ec-col-md-5, .ai1ec-col-md-6, .ai1ec-col-md-7, .ai1ec-col-md-8, .ai1ec-col-md-9, .ai1ec-col-md-10, .ai1ec-col-md-11, .ai1ec-col-md-12 {
    float: right !important;
}
