When copying from Grok xAI output ClickUp adds additional spaces to areas like bulleted lists and ordered lists. I don't have the issue with ChatGPT output and ClickUp. The issue occurs in Docs and Description fields of Tasks.
When copying the same text from Grok and ChatGPT to tools like Notion I don't experience the issue, which makes me hopeful that ClickUp might be able to do something to improve the experience.
