Hello Team,
No, you should not be concerned.
This is not an error, it is just information or say the Power Automate intelligence in action.
It is asking you to either configure one of the Select query, Filter query or Top count which it thinks you should enter to get better results as an output of Get records action.
These little information tips are designed to pop up so that someone who is very new gets to know that there are stuff like this in place that can help you fetch curated records rather then fetching the entire list of records.
You can ignore them for now, nothing is going to impact your flow.
