[FFmpeg-user] Is it possible to burn in two .srt files simultaneously to the same file?

[Media Mouth]

I've got 2 different .srt files and was hoping to use them both simultaneously to create burns in two different locations into the same video.

Currently I've got a watermark plus one .srt working just fine.  Was hoping to add the additional .srt.

The following CLI works just fine (ie Time code & 1 .srt file)
ffmpeg -i SourcePath \
-vf 'drawtext=fontsize=15:fontfile=/Library/Fonts/DroidSansMono-webfont.ttf:timecode='01\\:45\\:20\\:13':rate=23.976:fontsize=43.5:fontcolor=white:x=(w-text_w-35):bordercolor=black:borderw=2:y=75, subtitles=${SrtPath1}:force_style='Alignment=4,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff' \
DestPath

The following CLI fails (ie Time code & 2 .srt files)
ffmpeg -i SourcePath \
drawtext=fontsize=15:fontfile=/Library/Fonts/DroidSansMono-webfont.ttf:timecode='01\\:45\\:20\\:13':rate=23.976:fontsize=43.5:fontcolor=white:x=(w-text_w-35):bordercolor=black:borderw=2:y=75, subtitles=${SrtPath1}:force_style='Alignment=4,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff, subtitles=${SrtPath2}:force_style='Alignment=0,Fontname=Helvetica,FontSize=12,PrimaryColour=&Hffffff \
DestPath

The error points to the use of Helvetica font, but since the successful CLI above uses Helvetica as well with no problem, it sounds like a mislead.
