This seems to be a known issue for quite a while, see here:

As Wolfgang suggested there, you can use framed instead of TABLE in your
header. I have modified your example file (see attached). With that you get the
attached PDF.

By the way, your example was missing a \bTABLEhead. Moreover, I believe cells
in TABLE head entries should be enclosed by \bTH \eTH instead of \(b|e)TD. I
have made these changes as well.

[Also, I hope you are aware that you can use style=\tt, style=\bf per row/
column/cell with \setupTABLE; that will significantly reduce markup in your
file]
