Hi Informatics RN,
First, my pleasure to assist you.
As per your description, please don’t worry, we can work together to narrow down and resolve the situation.
It seems the column that has a "Person / Group " is showing as [object Object] and not the name of the Person.
I just tested from my side, and it seem I have no issue Person / Group coulmn. Here is my test image for your reference:
I believe, the Person/Group column appears as an object because if it has multiple fields: for example, city, state, first name, last name, etc. The data can, only show one field in each of the fields you select though.
As you mentioned, “I also have a connected Power app, which displays the data correctly, it is just the data in the list that displays the weird [object object] text” if issue only happened in SharePoint list, this is because person filed is treated as a lookup.
You may click on your problematic column>Column setting>Format this column and check JSON code to formating and there is a field called "txtContent", which can be given the value "@currentField". You may need to change “txtContent” field to” Person.title”
For example: “txtContent": "[$Person.title]"
I appreciate your understanding and stay safe!!
Best regards
