Comment (by mindctrl):

 @locke85 thanks for the extra details. I tried to reproduce this again,
 with just WP, Seriously Simple Podcasting, and the default 2025 theme, and
 I'm still unable to reproduce it.

 {{{
 === Environment
 - WordPress: 6.8.1
 - PHP: 8.2.27
 - Server: nginx/1.26.1
 - Database: mysqli (Server: 8.0.35 / Client: mysqlnd 8.2.27)
 - Browser: Chrome 138.0.0.0
 - OS: macOS
 - Theme: Twenty Twenty-Five 1.2
 - MU Plugins: None activated
 - Plugins:
   * Query Monitor 3.18.0
   * Seriously Simple Podcasting 3.10.4
   * Test Reports 1.2.0
 }}}

 I'm wondering if some other plugin or the theme is conflicting. Also, the
 podcast plugin registers its podcast post type on init at priority 11,
 whereas the default of 10 is most common. I wonder if, in your setup,
 changing that priority to 10 would make any difference. Either way, I
 don't think this is a WP core bug, unless it only surfaces with a certain
 configuration.

 Are you able to deactivate plugins, switch to the default theme, and see
 if it still happens? If it does not happen, start reactivating plugins one
 by one and see when it starts showing up again.
