Created attachment 133783 [details] picture of the problem We've been using a template ott for a while. We've realised that it is shown different in the new versions 5.3.x (For example 5.3.3.2 vs 5.2.2.7) The difference is in the text alignment in the header, where one row is used table to layout it. I attach a picture to show you graphically what I mean and a copy of the template to reproduce the problem.

Can not confirm on Windows 10 with Version: 5.3.3.2 (x64) Build ID: 3d9a8b4b4e538a85e0782bd6c2d430bafe583448 CPU Threads: 4; OS Version: Windows 6.19; UI Render: default; Layout Engine: new; Locale: en-US (en_US); Calc: group where layout of a new document using the template is the same as on Version: 5.2.7.2 Build ID: 2b7f1e640c46ceb28adf43ee075a6e8b8439ed10 CPU Threads: 4; OS Version: Windows 6.2; UI Render: default; Locale: en-US (en_US); Calc: group Turn on the "Formatting marks" View -> Formatting marks, or <Ctrl>+F10 to see the empty paragraphs. For me in both 5.3.3.2 and 5.2.7.2 the third cell of the table used for the Heading shows an empty paragraph entered in the template. Remove that extra line, and the document's header matches your 5.2.7 clip. Did the .odt template simply become corrupt gaining an extra line in that table cell?
Since there's no response, I'll close as WFM. Feel free to respond and set back to Unconfirmed.
