About Text Section Not Updating

I purchased the Therapist WordPress Theme (psychology-therapist-pro) and am currently building a website with it. However, I am having trouble changing the “About Text” in the “About Us” section of the “Theme Settings”. The changes I make are not reflected at all, and the content initially imported remains unchanged.

Other sections with editable textareas, such as the “Section Text” field in “Why Choose Us”, are being edited normally. I suspect this is not an issue with the TinyMCE invocation.

Could you please provide me with a solution to this problem?
