Captions Sidecar File not Created

I am also having this issue.  Using AME does not create a sidecar file.  If I export the SRT file using Premiere Pro, it exports, but completely loses all my styling that I did in Essential Graphics.  I would like captions, but don't want to burn them on the video (that seems to work).    When exporting from Premiere Pro, I chose to create the sidecar file.  It worked, but also completely lost all the formatting I did in Essential Graphics.  

Has anyone found a fix for these issues?  I really would like to have nice looking closed captioning, but not burned on my video.  I am using Premiere Pro 24.2.1 (build 2)

I have fully diagnosed the problem. It is a bug dealing with presets and the Create Sidecar File setting.

I have a preset for export with sidecar captions. It is based on my normal export with all my regular settings, but instead of "Burn Captions into Video" it has "Create Sidecar File" set in it.

When I choose export using that preset what happens depends on my export tool. If I export from within Premiere, it both burns in the captions AND creates a sidecar file. If I export from AME with that preset, it burns in the captions and does not create a sidecar file. I have tripled checked and yes, the preset does have "Create Sidecar File" checked.

When I select that preset in the export window, however, something broken happens. When I scroll down to captions, "Create Sidecar File" is already checked. But if I click on "Create Sidecar File" (it is already checked) the User Interface changes the preset to "Custom" above. So "rechecking" the Create Sidecar File setting appears to have changed something.

When I export using that "Custom" setting (again, it's my preset with nothing changed except I re-selected "Create Sidecar File") then two different options happen. If I export using this "Custom" setting from within Premiere, I get the desired results: no captions burned in and a .SRT file is created. If I export with AME, I get burned in captions and no .SRT file.

So the bug is in the handling of the Create Sidecar File setting both in the Presets and in transmission of that setting to AME.

How do I report this bug? Or is this good enough?

When reported in the past, this was due to one or more empty caption lines, and generally it was the first caption (a space or period character do not work). The symptom is as you describe: the media file would export, but no sidecar file.

BUT, this would also generally fail if the export was of srt from the caption tab, 3 dots menu.

And we did not sort every instance where this would fail.

I assume you have a Subtitle type caption track, and that you are selecting sidecar/srt in the export captions tab .
