Angular Google Maps (AGM) using multiple attributes

I'm trying to use the @agm/core to implement google maps API in my Angular app. I've tried using this documentation https://angular-maps.com/api-docs/agm-core/directives/agmcircle and following this example (among others): https://stackblitz.com/edit/angular-google-maps-demo?file=app%2Fapp.component.html.

Along those examples and documentation I created this sample of code:

  <agm-map [latitude]="+room.latitude" [longitude]="+room.longitude">

    <agm-marker [latitude]="+room.latitude" [longitude]="+room.longitude"></agm-marker>

  </agm-map>

Which works great. BUT, when I try to implement agm-circle:

  <agm-map [latitude]="+room.latitude" [longitude]="+room.longitude">

    <agm-marker [latitude]="+room.latitude" [longitude]="+room.longitude"></agm-marker>

    <agm-circle [latitude]="+room.latitude" [longitude]="+room.longitude"

                [radius]="5000"

                [fillColor]="'red'"

                [circleDraggable]="true"

                [editable]="true">

    </agm-circle>

  </agm-map>

I keep receiving errors. The error I get is:

ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'forEach' of null

TypeError: Cannot read property 'forEach' of null

    at AgmCircle.push../node_modules/@agm/core/directives/circle.js.AgmCircle.ngOnDestroy (circle.js:169)

I can't figure out if I'm using an old version of AGM or what. Is this API deprecated?

EDIT::

So this is weird, if I add +.3 or however any amount then agm-circle works without any problems.

  <agm-map [latitude]="+room.latitude" [longitude]="+room.longitude">

    <agm-marker [latitude]="+room.latitude" [longitude]="+room.longitude"></agm-marker>

    <agm-circle [latitude]="+room.latitude +0.3" [longitude]="+room.longitude"

                [radius]="5000"

                [fillColor]="'red'"

                [circleDraggable]="true"

                [editable]="true">

    </agm-circle>

  </agm-map>

Would anyone know the reason why? The forEach error seems totally irrelevant to what I did to not have the problem occur anymore.

EDIT::

Now that I'm able to recreate the problem causing this error: I figured out it has something to do with the observable "room".
