I keep getting a HTTP 404 error when trying to go to a Razor page

I'm working on a new Blazor app. This is the first Blazor app I've worked on since taking a Blazor course. I've added some razor pages as well. One of the pages never is found and always raises a HTTP 404 error, but the other pages are fine and can be found. Here's a code snippet from my _Layout.cshtml file:

<li class="nav-item"><a class="nav-link active" aria-current="page" href="/TimeTrackInputTime">                                Input Time</a></li><li class="nav-item"><a class="nav-link active" aria-current="page" href="/UserMaintenance">                                User Maintenance</a></li><li class="nav-item"><a class="nav-link active" aria-current="page" href="/InputTimeForUser">                                Input Time for User</a></li>

Both the InputTimeForUser.cshtml and UserMaintenance.cshtml files can be found fine. However, the TimeTrackInputTime.cshtml is never found. This is so frustrating, because they are exactly similar. All 3 files begin with this:

@page @model FP_Timetrack_Core.Pages.TimeTrackInputTimeModel

and even if I put in

@page "/TimeTrackInputTime"

it is still not found. I've double checked the spelling, and they are identical. I've not been able to find anything exactly like this issue.
