Visual Studio 2017 makes crazy indentation in CSS and Json

Question

Yesterday (Monday, 2017-05-15). I experienced that my VS17 started creating crazy indentation when I hit return for a new line inside a code block.

Example (json):

"Header": {
    "Title": "Hello world!",
    "Desc": "A test"
},

"List1": {
    "Item1": "Value1",
    "Item2": "value2"
}

Now, if I write "Item1": "value1", and then press enter, I expect the previous indentations to happen (just like last week, before I went on vacation). This week, however, it looks after recording and pressing enter:

"List1": {
                    "Item1": "value1",
                    | <- represents text selector
}

Now I checked all my indentation settings, and they are as before. I tried changing them back and forth for different settings, and nothing changed this behavior.
