Ion-input placeholder not showing up in macos

Ionic Framework
1

I have these ion-inputs:

<ion-input
mode=“ios”
class=“login-input”
style=“text-align: center”
shape=“round”
[clearOnEdit]=“true”
[(ngModel)]=“username”
placeholder=“Usuario / Correo”
>
<ion-input
mode=“ios”
class=“login-input”
style=“text-align: center”
type=“password”
[(ngModel)]=“password”
placeholder=“Contraseña”
>

But placeholders are not showing on macos, in any browser, in iphone and windows they are shown perfectly, what could be the issue here?
