Can't reproduce this on newest version of Dolphin. You are using rather old version, so you may want to report this to Ubuntu.

Comment 3 John Kizer 2025-03-14 04:46:03 UTC

Hi - I'm afraid Dolphin 23.08.5 is unfortunately no longer eligible for support or maintenance from KDE.

KDE projects typically move quickly, and bugs in one version are often fixed in the next one. Please update to Dolphin 24.12 as soon as your distribution offers it to you, or use other application distribution methods such as Flathub. If you need support for Dolphin 23.08.5, please contact your distribution, who bears the responsibility of providing support for older software in their "long-term support" releases.

If this issue is still reproducible in Dolphin 24.12, feel free to re-open this bug report.

Thanks for understanding!
