Same answer as the at the other topic. I think this might be a plugin conflict.
Could to try to disable all plugins except Pods and see if the issue persists?
In a live site I’d advice you to do this with the troubleshooter plugin: https://ww.wp.xz.cn/plugins/health-check/

Same as last ticket. We have to assume the issue has resolved itself as its been 2 weeks with no further comment.
