"Fields not usable in Wazuh Dashboard due to missing cached mappings"

Describe the bug
Hi ,
I have an issue regarding field in wazuh dashboard, where I am not able to use the fields.
It is showing "No cached mapping for this field. Refresh field list from the Management > Index patterns page"
As mentioned when I have done the refresh the fields will appear in the "wazuh-alerts-*" at that moment but again go back to how it was before refreshing.

I had checked about this issue and could only find "Refresh the field list" as a solution.
But, that is not working in my case. It just works for sometime and it is reverted back to how it was before refreshing the field list.

Here are some screenshots of the issue:

This is number of fields in "wazuh-alerts-*" before refreshing.

This is number of fields after refreshing "wazuh-alerts-*"

This gets reverted back to how it was before refreshing after sometime.

Also, I would like to point out that there is no problem with default fields.

All the solution got was to refresh the field list. But it does not work out.

Wazuh version being used is version 4.7

Looking forward for a solution for this issue.
