It's a sourcing problem. The problem is, those "everything sockets" are impossible to make in a safe and reliable form... and as such, UL will never approve one. Because of that, there's no such thing as an RU-Recognized (UL approved) socket, and people who make UPS's have no other choice but to buy cheap Chinese sockets. That means the sockets are not reliable.
So, this is a quality/warranty issue. Back to the store it goes.
The type of plug that you call "Type B" has a proper name: NEMA 5-15. It is made for 120V only! Philippines has 240V center-ground - and while that's unusual, there is a very similar NEMA 6-15 type which is designed exactly for 220V center-ground. If you must use a NEMA plug, use NEMA 6-15. However it probably won't play nice with the hokey "everything socket".
So stop using NEMA 5-15 for 220V. Use Europlug, BS1363, Schuko, Australian plugs, anything but NEMA 5!
A BS1363 in particular will be more reliable in those "everything sockets". I believe that is a type "G".
