Created attachment 204962 [details] zip file - contains test document and pdf beloning to I have found a wrong behaviour concerning the hyphenation. Although it already occured n LO 25.8 it is possibly related to Bug 168873 (only in 26.2). In a saved odt document for all paragraphs is set "Hyphenation: Automatic" in the paragraph's settings. When the document is opened some of these paragraphs are not hyphenated or they become not hyphenated while editing by some changes in the document although the hyphenation settings are not changed. Reproduce the behavior: - open the attached document "Paragraph_not_hyphenated_V8a_korr+saved_LO_25.8.4.odt" - with LO 25.8.4 or LOdev 26.2.0.0 beta1 (Information: The state of the document before it was saved is documented in "Paragraph_not_hyphenated_V8a_korr+saved_LO_25.8.4.pdf" - see corresponding revision timestamp on first page). On pages 6/7, 26/27, 36 and 46 there are 4 paragraphs marked with pale red background colour. Paragraphs on pages 6/7 and 26/27 show the behavior described in Bug 168873: - After the document is opened with LO 25.8.4 they are located correctly (wrapped). - When the document is opened with LOdev 26.2.0.0 beta1 the first of them is completely located on page 7. This causes a different formatting of the rest of the document. But when this is "repaired" by Enter + Undo (see below, -> paragraph wrapped on pages 6/7 again) now the second paragraph is completely located on page 27. This can also be repaired by Enter + Undo. But elevant to the now reported bug: The both paragraphs on pages 36 und 46 were hyphenated when the document was saved. The appearance after open depends on the used LO version: - When the document is opended with LO 25.8.4 both paragraphs are not hyphenated. - When the document is opened with LOdev 26.2.0.0 beta1 the first of them is hyphenated and the second is not hyphenated. But after the paragraph on pages 6/7 was repaired (wrapped from page 7 to 6/7 again) the hyphenation in the paragraph on page 36 is lost how already in the paragraph on page 46. In both cases the hyphenation can be easily "repaired" by setting the cursor before the paragraph and pressing "Enter" followed by "Undo" (Ctrl+Z). For me this is a serios error because I must check the complete layout of my documents (partly more than 150 pages) every time I open them. After small changes I have my "candidates" I have to check but after more extensive changes there are also unattended surprises. Some have even made it into printed copies – which is annoying for me.
