Problem with sprites slicing using TexturePacker

Hello. I’m using Texture Packer 4.3.3 for creating atlases.
Before I updated Unity to the 5.5 version everything was good.
But now I have a problem with sprites slicing if I want to republish sprite sheet:

New sprites is changing the atlas as always, but Unity didn’t see changes and slice it like the old version.
As the result we have something strange.

Yes, I can slice it by ny own in Sprite Editor, but it takes a lot of times and I don’t want to do it every time I publish sprite sheet.

Sorry for my english.

If i’m creating a new sprite sheet there is no slicing at all:

Hi,
are you sure you are using the latest TexturePacker Importer?

You might have to call “reimport all” on your assets after updating the importer.
