re-save-error in LibreOffice 25.2.3 for windows 11 64 bit

[Werner Marklewitz]

I have saved a new calc-table under a new name.
after open the calcble with its new name, i get in the head-line as new 
name "unbekannt.xltx" and not the new name.
when i save this calc-table i get the name "unbekannt.xltx" und not the 
opened path and new name.
