Firestore data not showing in dropdown on reactive forms

So I am trying to create a form array and want to populate the select field with some data from an observable coming from firestore. For some reason when I render the first form it populates but if I add any additional forms in the reactive array form it does not populate the dropdown. Is there something I am missing here that will allow it to show?
Here is the variable that gets the account observable
ngOnInit()
this.accountList = this.accountsCollection.snapshotChanges().pipe(
map((actions) =>
return actions.map((a) =>
const data = a.payload.doc.data();
return id: a.payload.doc.id, ...data ;
);
)
)
Here is the form array the *ngFor
is only populating the first one created but any created after the first does not have any values in the select dropdown. I am using the async
pipe to unwrap the observable.
<div formArrayName="debit">
<div *ngFor="let debit of debitForms.controls; let i=index" [formGroupName]="i">
<td class="rows">
<select class="input" formControlName="debitAccount" name="debitAccount" required>
<option value="" disabled selected>Select an account</option>
<option *ngFor="let account of accountList | async" [ngValue]="account"> account.name </option>
^^^ does not render any values after the first form of the array is created
</select>
</td>
<td class="rows"><input class="input" type="number" name="debitAmount" formControlName="debitAmount"
placeholder="Enter amount" /></td>
<td class="rows"></td>
<span class="button is-link is-danger" (click)="deleteDebit(i)">Delete</span>
</div>
</div>
