SSRS VS2015 SSDT report style selection screen is not displayed

Question

I'm at a dead end. I am not sure if others have the same problem.

In previous versions, when I use the report wizard, one of the screens allows me to choose a style (Slate, Forest ...)

With my new setting, the screen never appears, and on the summary screen it says "Style: Modern"

I tracked down StyleTemplate.Xml, made a copy and changed "Modern" to "ModernTest". And in the "Styles" folder, and in the "en" folder. I searched for my c drive and these are the only places this file exists.

EDIT: I had to change the label to "ModernTest", not the name. Now in the summary appears "ModernTest". However, I still do not get the opportunity to change the styles.

I added a new style to see if the page only appears if more than one is present, but perhaps since it was from an older version, it still thinks that there is one correct style, so it skips selection page ... I will try to reproduce modern ...

I am using VS2015 Version 14.0.25123.00 Update 2, SSDT Version 14.0.1601.5

Does anyone else have the same problem?

EDIT: I copied the xml file from the previous version, and now the slate appears as a style. I think the only problem is that the style selection screen is no longer displayed.
