JabRef version

Latest development branch build (please note build date below)

Operating system

GNU / Linux

Details on version and operating system

JabRef 5.5--2022-01-03--c94bb1b Linux 4.19.0-18-amd64 amd64 Java 16.0.2 JavaFX 17.0.1+1

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Create several groups
2. Select them
3. Right click on the selection and choose Remove groups > Also remove subgroups in the drop-down menu

You are prompted to confirm the deletion of one group. After accepting, this group is deleted, but you are not prompted to delete the other groups.
So, while it seems that several can be removed at the same time, groups can be removed only one by one.
