Indeed, the entry 'U.D.I.M. He 70' looks very strange.

But equally strange looks the line above: 'WL-D6KJ He 51'.
A 'WL-' reg points to the year 1939, early 1940 at best, so these two entries hardly correlate to a loss on July 17. 1942.
Plus 'D6KJ' could never be the four letters of a regular 'WL-' reg - the four letters should look like a civilian reg (starting with a vowel A/E/I/O/U/Y and not containing a numerial digit).

This raises the question:
How reliable look the remaining entries in this list?
