Katalon Multiple Custom Keyword Plugins - Show only the keywords from only one plugin

I wrote 2 custom keyword plugins.

  1. Simple Password Manger
  2. Read an excel file.

Build them as a Jar file using gradle. And dropped them into my katalon project’s “Plugin” directory. unfortunately, it only shows the keyword of Excel Plugin. I know both the jar files works perfectly fine. Because when I have only one jar file in the plugins directory it shows all the respective keywords.

Can any one please help me? I dont want to publish them on Katalon store. what am I missing? By the way both my plugins are fork of the Excel Keyword plugin.
