Importing PowerHTML module in a directory with a Types folder containing multiple .ps1xml files fails

I'm using PowerHTML is one of my modules, my module contains a `Types` folder with multiple .ps1xml files. When I am in my module's root directory and try to import the PowerHTML module, it fails with this error:
```
PS /Users/evan.yeung/git/OktaPS> Import-Module PowerHTML
Import-Module: The member 'FormatsToProcess' in the module manifest is not valid: The path cannot be processed because it resolved to more than one file; only one file at a time can be processed.. Verify that a valid value is specified for this field in the '/Users/evan.yeung/.local/share/powershell/Modules/PowerHTML/0.1.7/PowerHTML.psd1' file.
