I mean translation/rotation/scale.
You may have aligned your model and your armature in object mode instead of edit mode.
For example, maybe you scaled or moved your armature so that it exactly fits the model. You should have done this in edit mode.
Now there is a way to apply the Object transformations to the local transformation
Select your object, and hit ctrl + A. This will pop up an menu with all the transforms you can apply. I think “visual Transforms” apply the 3 type of transforms.
Do this on both the model and the armature
