License expire message showing up on production for goJs version 3.0.26

Hello, for our production use we got the license key for GoJs 3.0.11 in 2024 and this is valid for all the 3.0.* versions. Currently we are using 3.0.26 version but still getting this message in the top left of the canvas in our production
How to get this fixed ??

As you can see in the message, it appears that you are now using the 3.1 library, not the 3.0.26 library. Perhaps you upgraded to 3.1 unintentionally?
