Hey there, David! Thank you for your report.
I've passed this bug along to the engineering team, but because we're focused on delivering the all-new ClickUp 2.0 features as quickly as possible, this issue has been categorized as non-critical.
This means that it is unlikely to be resolved in the next few days.
I apologize for any inconvenience this may cause, and I thank you for your patience and understanding. I will be sure to let you know as soon as I have an update.
It does however look like this could be related to the titles of your notes. Do you have any empty space in these titles?
In the meantime, if there's anything else I can assist you with, please let me know.
