Why grid rows are not selectable?

Hi,
I have this grid on an Ionic4 app:

<ion-grid>

<!-- header -->
  <ion-row>
	<ion-col size="4">
	  {{ 'Time' | translate }}
	</ion-col>
	<ion-col size="8">
	  {{ 'Info' | translate }}
	</ion-col>
  </ion-row>

<!-- other rows not selectable -->
  <ion-row *ngFor="let data of filteredData; let i = index;">
	<ion-col size="2">
	  <ion-icon name="pin" slot="start"...></ion-icon>
	</ion-col>
	<ion-col size="2">
	  {{data['time'] | date: 'dd/MM/yyyy HH:mm:ss'}}
	</ion-col>
	<ion-col size="8" *ngIf="data['data_type'] === 'Position'">
	  <b>{{ 'Latitude' | translate}}:</b> {{data['latitude'] }} ; <b>{{ 'Longitude' | translate}}:</b> {{data['longitude'] }} ; <b>{{ 'Speed' | translate}}:</b> {{data['speed'] }}
	</ion-col>
  </ion-row>

</ion-grid>

I’m able to select with the mouse only the header of the grid, while the other rows are not selectable.
Why?
How does is it possible?
It could be a CSS issue, but there aren’t custom classes defined on the other rows.

Thank you

I’ve solved removing slot=“start” from the ion-icon tag…
