How to place a field on the left side in Modern UI

We can also use the Screen Configuration option from the menu once the field is added to the Modern UI.
To provide a more accurate and complete answer, could you please share screenshots or a brief explanation of the screen setup and requirement?

These are my two checkboxes: 

As you can see, they are placed on the right side, but in the Classic UI they look like this:

here is the code in my ts 

@columnConfig({textAlign: TextAlign.Left })
ReleasePOReceiptDuringFBAShipmnetImport: PXFieldState;
@columnConfig({textAlign: TextAlign.Left })
OverrideFBAShipmentBillToInfo: PXFieldState;

and html 

    <qp-fieldset id="CstPXLayoutRule234_fs1" view.bind="Store" slot="B" caption="FBA Default Shipment Options">
                  ...
                    <field name="ReleasePOReceiptDuringFBAShipmnetImport"></field>
                    <field name="OverrideFBAShipmentBillToInfo"></field>
                </qp-fieldset>

what am i missing?

​@Marat43  You have defined Slot=”B”. Try to modify it to ”A”

Ex:

<qp-template id="YourID" name="1-1-1"> 

<qp-fieldset id="CstPXLayoutRule234_fs1" view.bind="Store" slot="A" caption="FBA Default Shipment Options">

</qp-fieldset>

</qp-template>

Also you  can use, class="no-label"
