Great plugin but…

With debugging on, I keep getting this error message…

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the ultimate-post-list domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information. (This message was added in version 6.7.0.) 

I know the obvious answer is to turn off debugging, which I plan to do. But I figured the developers should know about it.

Please advise if this will be addressed in a future version or update. Thanks!!
