cant' filter genes when using Preprocessor

[doulijun777]

Hello, thanks for the amazing tool. And recent days when I run tutorial, I found that the gene is not filtered out using Preprocessor. See below:

adata = dyn.sample_data.zebrafish()
|-----> Downloading data to ./data/zebrafish.h5ad
|-----> File ./data/zebrafish.h5ad already exists.
xxxx/lib/python3.10/site-packages/anndata/_core/anndata.py:1756: UserWarning: Observation names are not unique. To make them unique, call .obs_names_make_unique.
utils.warn_names_duplicates("obs")

adata
AnnData object with n_obs × n_vars = 4181 × 16940
obs: 'split_id', 'sample', 'Size_Factor', 'condition', 'Cluster', 'Cell_type', 'umap_1', 'umap_2', 'batch'
layers: 'spliced', 'unspliced'
preprocessor = dyn.pp.Preprocessor(cell_cycle_score_enable=True)
preprocessor.preprocess_adata(adata, recipe='monocle')
