Extra padding on RadzenDatePicker

I am seeing some weird behavior with the date picker (v4.12.0). There seems to be extra padding to the right that I can't get rid of. This is what it looks like:

Here is the razor code:

<RadzenDatePicker Name="StartDate" @bind-Value=@QuestionModel.CreatedDate DateFormat="MM/dd/yyyy" />

How do I get rid of the extra padding?

I added the following to app.css to remove the extra padding:

.rz-calendar .rz-inputtext {
width: unset !important;
}

Now it looks like is should:

Is there a better way to fix this?
