Identified and fixed the actual root cause of duplicate settings page:
automatic instantiation in settings file being executed multiple times.
Root Cause Analysis:
- Settings file ended with: return new WC_TPP_Settings();
- File is in Composer's classmap for autoloading
- When autoloader loads class, it executes the entire file including instantiation
- Each include/autoload created a NEW instance despite admin singleton pattern
- Admin singleton prevented multiple admin instances but not multiple settings instances
The Fix:
- Removed automatic instantiation (return new) from settings file
- Settings file now only contains class definition
- Admin class explicitly creates instance: new WC_TPP_Settings()
- Changed from include to require_once to prevent multiple file loads
- Settings instance now created exactly once, when filter needs it
Fixes:
- Settings page rendering twice in WooCommerce backend
- Multiple WC_TPP_Settings instances being created
- Composer autoload triggering unintended instantiation
Changes:
- Removed line 145 from class-wc-tpp-settings.php (return new WC_TPP_Settings())
- Modified add_settings_page() to use require_once + explicit new
- Settings file now side-effect free, safe for autoloading
Technical Details:
- Composer classmap autoloader includes files when class is referenced
- Previous code had side effect (instantiation) on every include
- New code separates class definition from instantiation
- Instance creation now controlled explicitly by admin class
- require_once ensures file loaded once even if accessed multiple times
Updated Files:
- includes/class-wc-tpp-settings.php (removed return new line)
- includes/class-wc-tpp-admin.php (explicit instantiation)
- wc-tier-and-package-prices.php (version 1.1.18)
- composer.json (version 1.1.18)
- CHANGELOG.md (v1.1.18 section)

Fixed settings page appearing twice in WooCommerce settings due to double instantiation of WC_TPP_Settings class.
**Issue:**
- Settings page rendered twice on same page
- WC_TPP_Settings class instantiated twice: once automatically in settings file, once via admin class include
**Fix:**

- Restored v1.1.2 pattern for settings file
**Files Modified:**
- includes/class-wc-tpp-settings.php (simplified return statement)
