"Fliplr", after applying this operation labels got disturbed

[harsh123-baba]

Hey..
i applied augmentation using imgaug but when i applied augmentation with given code
seq = iaa.Sequential([
iaa.Affine(shear = {'x':20, 'y':0}),
iaa.Fliplr(0.5),
iaa.Sometimes(
0.5,
iaa.GaussianBlur(sigma=(0, 0.5))
),
iaa.LinearContrast((0.75, 1.5)),
iaa.Multiply((0.8, 1.2), per_channel=0.2),
], random_order=True)

so i am getting result as

then i applied same function by commenting flipir part so it working fine
iaa.Sequential([
iaa.Affine(shear = {'x':20, 'y':0}),
# iaa.Fliplr(0.5),
iaa.Sometimes(
0.5,
iaa.GaussianBlur(sigma=(0, 0.5))
),

so can you suggest me anyone else is facing same issue
