Ionic + Angular

Question

Help please,

I tried to fix it without success. I'm using Ionic framework and Angular. I have a form which is opened when I click on a Sidemenu. So the problem is when I add a formControllerName on the input field it modified my design's form. I don't understand why these input can change my form. I imported everything in my module's page where I needed.

1. my form without formControlName form_1
2. my form with formControlName Form_2 Input
