Why Levenshtein Corrector make strange inserts inplace of punctuation marks?

Created by: takiholadi

from deeppavlov.deep import find_config, deep_download
from deeppavlov.core.commands.infer import build_model_from_config
config = find_config('levenshtein_corrector_ru')
deep_download(config)
model = build_model_from_config(config)
print(model(['Сегодня.']))
print(model(['в 3 . Сегодня.']))

Gives me

['сегодня в'] ['в 3 и сегодня и']

There are strange "." --> "в" and "." --> "и" inserts.
