Weird indentation behaviour for TYPES: (with colon) in Editor

Hello,

in the protected section of a class, there is a weird behaviour for indentation when pressing ENTER.

Here is the source code before pressing ENTER:

The cursor is in line 22, column 5 before the "TYPES:". Now, when I press ENTER, it looks like this:

The "TYPES:" is indeted, the new column position is 14.

I would have expected no indentation at all. This does not happen, if I have a TYPES notation without the colon (:).

Any idea, why this behaviour occurs?

I think, I have the latest ADT version. Here is the version details:

Thanks for any help in advance!

Best regards,
