revprintfield and RIGHT tabalign?

[Klaus major-k]

Hi friends,

I am trying to print a field, but when it comes to a right aligned TAB
things go awray in the resulting PDF/printout.

LC 9.5.1, macOS 10.14.6

Please take a look here:
<https://major-k.de/temp/revprintfield.jpg>
LC field on the right, PDF on the left.
At the bottom the TAB align and TAB stops of the field to be printed

Please note the unwanted wrapping of the first two "TOTAL für..." lines!?
But it only wraps if the text exceeds a certain length? 
No wrapping if I only supply the actual SUM in the TOTAL line. 
What am I missing?

Thanks for any hints!


Best

Klaus
