Extra comma in entry preview

[reox]

JabRef version

JabRef 5.1--2020-06-02--46fd96b
Linux 5.6.0-2-amd64 amd64 
Java 14.0.1

on
Debian testing/sid

• Mandatory: I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Steps to reproduce the behavior:
Each entry in the preview has an extra comma in the title string.

biblatex entry:

@Article{Venkataraman_2012,
  author     = {Vivek V. Venkataraman and Thomas S. Kraft and Nathaniel J. Dominy},
  title      = {Tree climbing and human evolution},
  doi        = {10.1073/pnas.1208717110},
  number     = {4},
  pages      = {1237--1242},
  volume     = {110},
  journal    = {Proceedings of the National Academy of Sciences},
  month      = dec,
  publisher  = {Proceedings of the National Academy of Sciences},
  year       = {2012},
}

looks like this:

See the extra comma in "Tree climbing and human evolution,"

Thanks for reporting this issue. Could you please tell us if you are using the JabRef Preview style or any other of the CSL styles?

Honestly, I did not even knew there was a setting :D
you mean this here?

Looks like I'm using IEEE.

[Siedlerchr]

Yes, that's what I meant.
In the Entry Preview in the entry editor you can cycle through the selected styles using F9.
All Styles except the Preview are from the https://citationstyles.org/ repository.
And I also took a quick look, it's correct IEEE style to have a comma after the Title. https://ieeeauthorcenter.ieee.org/wp-content/uploads/IEEE-Reference-Guide.pdf

Okay I see, looks like I must have accidentality pressed F9 and was lost then...
Thanks for pointing this out. I do not quite understand why IEEE has the comma inside the quotation marks - but okay, if they like it that way ^_^
