some features are missing after resampling

[Evan-Ning]

Hi, thanks for the package. I'm running into this problem. I have a dataframe with 20 columns/ features. It seems that after resampling with smogn, I end up with only 15 columns.

My code looks like this:
rg_mtrx = [
[40, 1, 0], ## over-sample ("minority")
[0, 0, 0], ## under-sample ("majority")
]
train_set_smogn=smogn.smoter(
data=train_set.reset_index(drop=True),
y='count',
#k=10,
k=5,
pert=0.04,
samp_method='extreme',
rel_thres = 0.1,
rel_method = "manual",
rel_xtrm_type = "high",
rel_coef = 0.01,
rel_ctrl_pts_rg = rg_mtrx
)

x_smogn=train_set_smogn
x_smogn=x_smogn.drop('count',axis=1)
y_smogn=train_set_smogn['count']
