My custom plugins have updates? =S

What information did you put in the plugin header? The code that checks plugins on the back end can get confused sometimes, if your info is too similar to some other plugin already in the plugin listings.

This is whats on the top of my plugin…

/*
Plugin Name: Link Replacer
Plugin URI: https://im1music.net
Description: Replaces specified links
Version: 0.1
Author: iM1
Author URI: https://www.im1media.com
*/

Probably matching against this one: https://www.ads-software.com/extend/plugins/link-replacer/

The plugin matching can be a bit hit or miss. Best to use a really custom name when using custom plugins. Like something specific to your site. Such as “im1media.com Link Replacer” or whatever.
