How to use mne_bids correctly?

Dear forum members,

I am curious about why mne_bids will change my events_id after saving raw data into BIDS. The structure is nice, which convenience my work, but the changed events_id make me doubt about the correctness of events_id.

Thank you and wish you a nice day!

Before transforming format into BIDS, I get events and event_id as following. The key value is correct as experimental program.
