Why is the text typed as if it were in mirror image?

Why is the text typed as if it were in mirror image? I have the libre version 5.4.1.2, and iOS 10.12.6 Sierra

Do you have enabled right-to-left writing accidentally?

upvoted @MATEUSZ1, please upload a screenshot of the mirrored text, by editing your original question.

Regina: I did not write right to left. The document was already created before the update
