Text Size and Alignment in Projects

Previously (last year), I successfully created, edited, and printed a big project with a large number of manually created elements.

Now I need to return to this project to make some changes. However, when I opened it, I found that the text no longer matches in size and position. This affects the entire project, including both the elements themselves in the Element Editor and the positions of labels and textfields, as well as the text in title blocks.

It seems that the program’s settings are overwriting the text settings in the project.

Please advise how to fix this and how to avoid similar situations in the future. Thanks in advance!
