removing Depends On entry still shows "Pending" and old dependency in Projects view

[jasonrush]

I'm running TRACKS (says version 2.5.2 at the bottom of the webpages) as a Docker container via Synology's package manager (Synology's package automatically deployed it, I did not manually deploy the Docker container). Per the Synology Package Center, the Synology package is v3.4.13-0054.

I've created a project, added a bunch of actions (using the "Multiple next actions" and checking "Make actions dependent on each other" options), then realized the last action in the chain wasn't really dependent on anything else. I edited the action, removed the Depends On entry, and clicked the "Update" button, form submitted successfully.

On the Project page, it still shows the action under "Deferred/pending actions in this project" section, shows the orange "Pending" box which when I hover over it shows that it depends on the action it used to depend on, but when I click into the Edit form, it doesn't show it depends on anything. I have refreshed the page (including shift-F5 which I believe refreshes w/o caching in Chrome), I've added a new depends on, updated, then removed and it's still doing the same thing only hovering over the orange "Pending" box shows it depends on the new one I had temporarily set it to depend on.

Expected behavior would be that it no longer shows in the "Deferred/pending actions in this project" section and no longer shows the orange "Pending" box, instead showing under next actions.
