Wrong automapping and an error "No signal mapping ..." on download.

1/ Open the attached project;
2/ Navigate to Gateway's page "Signal Mapping". No mapping can be seen although the mapping mode is "Auto" -> this is an error;
3/ Switch automapping to "Off";
4/ Switch the automapping to "On" again -> mapping is seen in the page, however it is wrong;
5/ Download -> an error occurs: "No signal mapping ...", although in the page a mapping can be seen.
