incorrect translate in

I think there is a mistake in your RTL bootstrap and must be change to:

.input-group .form-control:first-child,
.input-group-addon:first-child,
.input-group-btn:first-child>.btn,
.input-group-btn:first-child>.dropdown-toggle,
.input-group-btn:last-child>.btn:not(:last-child):not(.dropdown-toggle){border-top-left-radius:0;border-bottom-left-radius:0}

So to solve this issue i have changed right with left.
