Single filter is not updateing the chart on change.

[MikePageDev]

I initially set it up with the form version, and it worked fine, but I switched to the single version because I'm only using a single filter. When the chart loads, the default filter loads fine, but nothing happens when I change the dropdown, and I can't see anything in the network tab. If I set polling to 10s and change the dropdown, the chart updates correctly after 10s, so my query works fine. It looks like the dropdown is not triggering a reload. Any thoughts?

Here is the chart class

<?php

namespace App\Filament\Widgets;

use App\Http\Controllers\TrainingSubjectController;
use App\Models\TrainingSubject;
use Carbon\Carbon;

    protected static ?string $chartId = 'trainingSessionChart';

    /**
     * Widget Title
     *
     * @var string|null
     */
    protected static ?string $heading = 'Training Sessions';
    protected static ?string $pollingInterval = null;
    protected static ?int $sort = 3;
    private $trainingSubjects;
    private Carbon $start;
    private Carbon $end;
    public ?string $filter = 'week';

   {
       $this->trainingSubjects = TrainingSubject::get();
   }
