error when loading new FOV with single-cell features widget, the layers need to be cleared

[mattersoflight]

If an FOV is already loaded in napari (say, 0/0/0, trying to load another FOV, say 0/2/0) throws the following error.

File /hpc/mydata/shalin.mehta/envs/ndutils/lib/python3.11/site-packages/napari/layers/_scalar_field/scalar_field.py:381, in ScalarFieldBase._get_level_shapes(self=<Image layer 'DIC'>)
    379     shapes = data.shapes
    380 else:
--> 381     shapes = [self.data.shape]
        self = <Image layer 'DIC' at 0x7f054df50750>
    382 return shapes

The error only occurs if the layers from 0/0/0 are populated before.
