Created & edited time in 24-h format

While I choosed the 24-h format of time display in preferences, when I move the mouse to the little black point of the items, it didn’t show a 24-h format. It showed “created at 下午9:30:30 on 2020/5/12, last edited at 下午9:40:30 on 2020/5/12”. However I’m not used to read ”21:30:30" as "下午9:30:30“ or “9:30:30 pm”. Now the 24-h format didn’t work, hope the created & edited time display in 24-h format.
