ngx-material-timepicker: Time range selection (min, max) not working correctly

We’re using ngx-material-timepicker in our project and came across an issue in range time selection. Here is input element for time-picker.

<input matInput type="text" [ngClass]="{'time myInput': true, smallFont: popupView}" formControlName="time" [ngxTimepicker]="picker" placeholder="Add time" min="09:00 am" max="03:00 pm" readonly>

<ngx-material-timepicker [ngClass]="{'timePicker': true}" (timeSet)="onTimeSet($event)" #picker></ngx-material-timepicker>

Expected: It should allow to select anytime between 09:00 am to 03:00 pm.

Problem: 12:00 pm to 12:59 pm can’t be selected. Event though it lies within the above range.

Two screenshots are attached to support above argument.

Thanks in advance for any help!
