When you include a file inside a module definition, all the contents of that file is loaded into the module scope. So, you have modules `Main.ModuleA.MyParams` and `Main.MyParams`, which the system considers different.

There have been discussions recently on how to organize code in such cases, you may find and try different suggestions to choose from:  
([Writing functions for types defined in another module](https://discourse.julialang.org/t/writing-functions-for-types-defined-in-another-module/31895))  
([What is the preferred way to use multiple files?](https://discourse.julialang.org/t/what-is-the-preferred-way-to-use-multiple-files/30687))

Also, please see this topic ([Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757)) for tips on formatting.
