    The maximum jump in upgrade version you should do is 3 EEOL (extended end of life) releases.  Your upgrade here was 4 versions.  These types of oddities are what can occur with larger than expected jumps.

    So you should probably rollback the upgrade.

    Then since you are coming from the x version releases the safest path is to make the first of two upgrades to the closest general release.  This would be 17.4  in your case.  

    Then make the second upgrade to the final version from there.
