Parameter names that use a mix of both uppercase and lowercase names, Dialogflow automatically uses lowercase names when tagging training phrases (on the training tab) for “parameter name”, when those same phrases are added to the model (using the check mark), the tagging of the parameters are not kept, so the user needs to manually change the “parameter” name from all lowercase to the correct one that has a mix of both uppercase and lowercase characters

Problem you have encountered:
In the above steps, click on the highlighted balloon. Note the parameter name - lowercase "producttype" and no entity.

What you expected to happen:
 For Dialogflow to automatically tag the training phrase as the parameter names were originally entered, whether all lowercase or uppercase or a mix of both


Steps to reproduce:
Import the attached agent. In the “try it now” window, type "product inquiry balloon" and hit return. After that "yes" and return. Click on the training tab. Selected the top entry (what you just did). See the phrase "product inquiry balloon" with "balloon" highlighted. Click on the highlighted balloon. Note the parameter name - lowercase "producttype" and no entity. Adding this training (check mark and approve) to the intent loses the parameter.


Other information (workarounds you have tried, documentation consulted, etc):
 If you manually change the parameter in the tagging from the incorrect lower case version (done by DF) to the correct one with the mixed upper and lower case parameter name @productType:productType and then approve it, it will work correctly
