Dear Smith,
Thank you very much for the report and I am very sorry about the experience!
Unfortunately, this is a limitation of Archicad, recorded as #254998. The reason behind this behavior is that the "Horizontal Text" does not really work for Elevation Dimension in this case, but it was not removed either. Thus, it created the result as on the screenshots you have attached.
I am very sorry for the inconvenience, and thank you very much for your understanding! Please let me know if I can assist any further in this case!
Thank you very much!
Best regards,
Minh
