[TYPO3] Flexform: unwanted output DEF:

[Matthias Stuebner]

Good morning all,

I used flexforms the first time and it works fine. the only thing I
couldn't figure out is the follwing:

Above the first tab of the flexform I see a bold and black "DEF:" and have
no idea where it comes from. As fas as I can see it doesn't come from the
xml file, nor out of the language.xml. 

Any other idea or hint? Again, the form works perfect, it is just the
unwanted output I wonder about.
