PI- Scanning is not working for 5 mins chart. But working for 1 min chart

Hi All,
Facing issues like - not blinking and accepting the condition in 5 mins chart. But if i verify manually my condition is satisfying. But the Scanner is not working as expected. Same condition is working fine in 1 mins chart. I am not sure is this issue with PI Scanner or Delay of Scanning (Delay means - 1 mins chart also should not work, but 1 mins working fine as expected).
Looking for the help here for PI Scanning. I am able to share the details if required.
