Some ui component not work after update

hi there,

i have updated all my ionic project and i encounter strange render in some component.
i compiled with gradle v5.x, android sdk is 19 from 28.

  • Strange render 1 example with ion-label and ion-input:
// from standard ionic code with angular formcontrol name

<ion-item class="input_type">
      <ion-label floating>type</ion-label>
      <ion-input formControlName="type" type="text" [(ngModel)] {etc ...} </ion-input>


  • no personal css added
  • any input text can be enter, i can’t see them cause they don’t exist :sob:
  • any error and warning in browser

  • Strange render 2 example with ion-select
// code from ionic-select documentation
      <ion-select placeholder="Select One">
      <ion-select-option value="f">Female</ion-select-option>
      <ion-select-option value="m">Male</ion-select-option>


  • no personal css added except border, width and height
  • without this fiew css it’s just the same render but it’s mini-small
  • any error and warning in browser

  • Other Informations :

I think angular version don"t match the newer but i don"t really know :grimacing: it’s juste a (bad) supposition

Like said i have tried to update all and i don’t really know if versions match together, this is my ionic info and my package.json.

  • Could u confirm me if these versions(ionic, cordova, angular) work together please ?

  • Maybe do u have some indication about UI bug i encounter please too ?

have a nice day,


solved by declaring this component with problems in module of page using it
instead of :
declaring this component in component.module and import this last in module’spage using the component rendering problems
