Deprecated Filter Error

I am using the latest version of AISEO (version 4.1.9.4) and am receiving this warning error in my console:

Deprecated Filters Detected
27 minutes ago
Warning: AIOSEO has detected the use of filters that have been deprecated on your site. These filters may be in use by another plugin or your theme. If that is the case, these filters most likely will not work with this plugin. Please make sure you have updated all your plugins. If you have manually added these filters, please check out our documentation for the updated filters to use.
aioseo_custom_menu_order

I am not aware that I have done anything on my site to “customize” AISEO, so I am not sure why I am receiving this message.

Any help/assistance would be appreciated as to where to look for errors.

Regards,

Michael
