I'm trying to build a simple filter-bar which has a custom-control element.
The element should be aligned vertically but it seems not to be working. This is the markup for the filter-bar:
<div class="bg-light p-3 card">
<form class="form-inline">
<div class="form-row">
<div class="col-auto">
<input type="text" placeholder="The team's name" class="form-control" value="" />
</div>
<div class="col-auto">
<select class="form-control">
<option value="">Select the season</option>
<option value="2019">2019</option>
<option value="2020">2020</option>
</select>
</div>
<div class="col-auto">
<button type="submit" class="btn btn-secondary">
<i class="fas fa-search"/> Search</button>
</div>
<div class="col-auto">
<div class="custom-control custom-switch align-center">
<input type="checkbox" class="custom-control-input" id="vpx" checked="" />
<label class="custom-control-label" for="vpx">Hide 0-point teams</label>
</div>
</div>
</div>
</form>
</div>
But the result is shown below:
No matter which align- class I add, the element won't move a bit. Already tried to set the display property to inline-block as stated in the bootstap-docs.
Only way to achieve something like centered is to add mt-2 class but this seems not to be the correct way this should be done.

Add align-items-center to form-row and also close the <i> tag correctly on Search button
body{ min-width: 800px;}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="bg-light p-3 card">
<form class="form-inline">
<div class="form-row align-items-center">
<div class="col-auto">
<input type="text" placeholder="The team's name" class="form-control" value="" />

<div class="col-auto">
<select class="form-control">
<option value="">Select the season</option>
<option value="2019">2019</option>

</select>
</div>
<div class="col-auto">

<i class="fas fa-search"> Search</i></button>
</div>

<div class="custom-control custom-switch align-center">
