timecode and srt export

Can someone help me with this, please.
I have a 24fps sequence on timeline with subtitles. When I exported them in srt file, picture shows the result.
But, as you can see from Resolve srt text file, there are 3 digits at the end. Don`t get it!?
Should it be two digits instead, fallowing number of frames (00-24 then back to 00)?
Should it be "hours: minutes: seconds: frames:!?
Is there any other export option to get it right ? Is there a settings that I missed in preferences?
