Hi Tim. It's not a real bug. It is just regular AMOS maintenance task. AMOS has it's own list of components that should be considered as standard ones. Currently, this list is maintained manually. I update the list from time to time, more frequently when a new release is to come. The list just was not yet updated for 3.0 so the components were not marked as standard ones.
I just deployed a fix to the lang.moodle.org site that adds all ddimageortext, ddmarker, ddwtos and gapselect to the list of standard components.
As far as I can see, the qtype_ddimagetoimage mentioned above has not landed as a standard plugin so it is still enlisted as additional one in AMOS - and the en_fix can't be used for it.
Hope this helps and I do not miss something (in which case, MDLSITE issue is the best way to sort it out).
