Cannot complete tasks

Question

Hello,

we've been using Confluence for couple of years and now, we run into a problem. We are unable to complete some tasks. 
How it happens. We have page1. On the page there is multiple tasks. For upcoming meeting we copy the page and remove all the task and create new ones.

Problem happens when we want to complete tasks on page1. The error is:
"Oops! Your task change couldn't be saved"

Does anyone know what's the problem and how to mitigate it.

Thanks,

M. Krajnak.

Hi @Muhammad Ramzan_Atlassian Certified Master_
thanks for response.

See the screenshot, this is the type of tasks I am talking about.

It's called Action Item in Confluence.

Which tasks you are referring here, are those Jira tasks or you have something on Confluence itself ?
