Merge in PS with HDR PRO (Bridge v.11 and PS v.22)

[Pierluigi6C12]

Selecting some files in BR (may vary from 3 till 16) then Merge in PS with HDR PRO, selecting 32bit and Tone in ACR, the resulting file is completely wrong/corrupted, generally under-exposed but also without any color/dinam range absent. What could be happened ? before the update everything works well. Thanks in advace for every kind of help, Regards.

If it was me ..............

I would first , limit your image selection to no more then six images, and then choose based on the widest exposure difference between each one. 

BTW what type of files are they?

thank you for your suggestion, but before the upgrade I've often used this method for multi-exposure photo and always worked well. The source file are CR2, raw file of my Canon. I'm going to restore old version

Just an update: working with tiff files, directly from PS it works correctly.  If I use CR2 files, manipulated in Camera Row, or Tiff file, then open in PS as HDR Pro, there are problems, so I guess that there are some issues working in Bridge then passing the file in PS
