Impress - copy/paste box with text doesn't allow text to be edited

Hi,

Only recently starting to use Impress for work, and struggling with a very simple thing. Surely its something I am doing, but I just cant work it out.

I create a box, and add some text. I want to make more boxes the same size, so I copy/paste the box and expect to edit the text for the new object. In the new box though, the text cannot be changed, and instead it writes new text over the top (so the box gets the old text with a new layer of any new text).

Any idea what I am doing wrong ?

Edit:
OS - Linux, Fedora 41
Desktop - KDE Plasma
LibreOffice Version - 25.2.2.2 520(Build 2)

Thanks, added these

It turns out that in LibreOffice Impress, a text box is a drawing object.

Therefore, if you copy and paste directly with the mouse or with Ctrl+C / Ctrl+V, the object is sometimes interpreted as a drawing object with text content.

This means that when pasting, you cannot directly access the internal text editing mode, and it would remain as a new box. Double-clicking or entering edit mode should allow you to change the text in it.

Possible solutions to resolve the problem include:

Using double-click to enter text editing mode:

Check the KDE clipboard settings, which uses Klipper as the clipboard manager. Sometimes, certain copied formats are not transmitted correctly if Klipper is incorrectly configured.

In System Preferences —> Clipboard, try disabling synchronization; this sometimes modifies strange behavior when copying and pasting between graphical applications.

Thanks for this. You are exactly right, it is “sometimes” being detected as an image.
Plasma has a clipboard tool wl-clipboard/wl-paste which gives mime information.
Sometimes I am getting :
wl-paste -l
application/x-qt-image
image/png
image/avif
image/bmp
image/bw
image/cur
image/dds
image/eps
image/epsf
image/epsi
image/exr

sometimes:
wl-paste -l
application/x-openoffice-objectdescriptor-xml;windows_formatname=“Star Object Descriptor (XML)”;classname=“9176E48A-637A-4D1F-803b-99d9bfac1047”;typename=“LibreOffice 25.2 Presentation”;viewaspect=“1”;width=“6503”;height=“4003”;posx=“0”;posy=“0”
application/x-openoffice-embed-source-xml;windows_formatname=“Star Embed Source (XML)”
application/x-openoffice-drawing;windows_formatname=“Drawing Format”
application/x-openoffice-gdimetafile;windows_formatname=“GDIMetaFile”
application/x-openoffice-emf;windows_formatname=“Image EMF”
application/x-openoffice-wmf;windows_formatname=“Image WMF”
image/svg+xml;windows_formatname=“image/svg+xml”
image/png
application/x-openoffice-bitmap;windows_formatname=“Bitmap”
image/bmp

I am going to try and work out when each occurs …
