One structure produces two canonical tautomers

This was tested using Marvin 14.10.27.

I have two different drawings of the same structure.  When I calculate the Canonical Tautomer from MarvinSketch (with the Rational Tautomer generation box checked) I get two different results.

 Both input structures (see attached file) should produce the same canonical tautomer.  Please fix.

Dear Tim, 

we have reproduced the problem, and it turned out to be a bug. We will fix it soon. The next release will have the fix. 

Best regards,
