Incorrect conversion docx to epub

[wangying]

Platform
 Windows 10
 Calibre 7.9

I converted a docx file into an epub file and found that many spaces were missing.

The original text is like this:

MBTI on the basis of the wisdom he gained from developing mindfulness-based cognitive ther- apy. I would also like to thank Edward Stepanski, Sandy Gramling, and Roseanne Armitage for their mentorship early in my training.

After the conversion, it looks like this:
