Sentence segmentation is not working as per the golden rule for sentence "At 5 a.m. Mr. Smith went to the bank. He left the bank at 6 P.M. Mr. Smith then went to the store."

Sentence segmentation is not working as per the golden rule for sentence "At 5 a.m. Mr. Smith went to the bank. He left the bank at 6 P.M. Mr. Smith then went to the store."

It is creating four sentences
'At 5 a.m. ',
'Mr. Smith went to the bank. ',
'He left the bank at 6 P.M. ',
'Mr. Smith then went to the store.'

Instead, as per the golden rule, it should have created three sentences
"At 5 a.m. Mr. Smith went to the bank."
"He left the bank at 6 P.M."
"Mr. Smith then went to the store."
