Wrong timings of srt subtitles files

I'm exporting an .srt subtitles file (both with and without formatting) for a YouTube video. Unfortunately, although the subtitles start at the beginning of the video in Davinci Resolve, all the subtitles are delayed by three seconds. For example, instead of starting at 1:00:00,599, they start at 1:00:03,599. This timing issue affects all the subtitles, and I have subtitles in two different languages, both of which are being exported incorrectly. I even tried exporting in a different format, such as .vtt, but the problem persists.

Am I missing something? Is there a specific setup required for my system?

Thank you so much for your help!

Best regards,
Andres
