It sounds like there might be a conflict between the settings of your SEO plugins and how your website’s theme handles title and description tags. Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check Theme Settings: Sometimes, themes have their own settings for managing titles and descriptions. Make sure that your theme’s settings are not overriding the settings from your SEO plugins.
2. SEO Plugin Settings: Review the settings of each SEO plugin you’re using. Look for options related to title and meta tags, and ensure they are configured correctly to display the desired format.
3. Plugin Compatibility: Check if there are any known compatibility issues between your SEO plugins and your website theme. You can do this by searching online forums or contacting the support teams of the plugins and theme.
4. Plugin Conflict: Sometimes, using multiple SEO plugins can cause conflicts. Try deactivating all but one of the plugins and see if the issue persists. If it doesn’t, gradually reactivate the other plugins one by one to identify which one is causing the problem.
5. Code Customization: If none of the above steps work, you might need to customize the code of your theme to ensure that it properly integrates with your chosen SEO plugin. This might involve modifying template files or adding custom functions.
6. Consultation: If you’re not comfortable making code changes yourself, consider hiring a developer or reaching out to the support teams of your theme and SEO plugins for assistance. They may be able to provide specific guidance tailored to your website’s setup.

Remember to backup your website before making any significant changes, especially if you’re going to modify theme files or plugins. This ensures that you can easily revert to a previous state if anything goes wrong during the troubleshooting process.
