no index

Hi, I am marketing manager at a startup called Ndovucloud technologies.
We had installed the rank math plugin to help optimize our blog posts but when we went to look at search console we noticed we had a number of coverage issues. Our blog posts had the no index tag. We have checked everything from the actual settings of the CMs under the reading section to the actual setting of Rank math plugin –> Titles & Meta –> Robots & meta. From doing all these check we found that the blog post have been allowed to index yet when we look at the source code of the blog posts affected we find rank math has placed a no index tag on them.
We have done all our checks and suspect it could be the plugin causing this some how can you assist. Find Below some of the Blog posts you can view their source code to see the current issues we are facing
