Bug LightLayerEnum.Everything and DecalLayerEnum.Everything serializes to different values.

unity 2021.3.11

Code (csharp):

1.  
2. public LightLayerEnum lightLayerMask;
3. public DecalLayerEnum decalLayerMask;
4.  

And when I select in inspector "Everything".
The Yaml file looks like this:

Code (csharp):

1.  
2.       lightLayerMask: 255
3.       decalLayerMask: -1
4.  

As a result decals set to everything are setting all this unused fields in a mask.
When on light layers only light layers are selected.

The question is, is this intentional behavior ?

I think not since
DecalLayerEnum.Everything = DecalLayer7 | DecalLayer6 | DecalLayer5 | DecalLayer4 | DecalLayer3 | DecalLayer2 | DecalLayer1 | DecalLayerDefault,
