Microsoft visual basic 6 warning in relation to a newer version of tlb

Question

I am working with a very large code base composed of several groups of projects in vb6.

Every time I open the group project I'm prompted with several of these pop-up messages asking me if I want to upgrade to the new version of the .tlb

I know these get created when we register the dlls but I'm not sure how to get rid of these messages, I usually just click yet to all of them and the project loads fine. Is there any way I can remove these or set the version to load as the new 21.1 version by default?
