Is this UPS Socket Defective?

Question

I have 2 UPS of the exact same model. In one UPS, all of my Type B Plugs would not fit
In the first image, the hole on the socket is on the edge. My Type B Plugs (3 pin) would not fit. On the second image, the hole on the socket is on the middle and my Type B Plugs (3 pin) would fit. For reference, the last image shows what a Type B Plug looks like.

Edit: As it might be a "Fake" I included the picture of the serial number of the back of each UPS.
The first image shown is the UPS' serial with the plug that fits. The second image shown is the UPS' serial where the plug does not fit.

That is a valid type of socket. See the APC manual for the BX-1400 MS.
However, I would be extremely careful plugging any US type B plugs into this UPS. As far as I can tell, this is a 230V UPS. The US type B (aka NEMA 5-15) is normally used for 120V devices. If your device comes with a type B plug and, like most but not all computers, monitors and laptop power bricks made in the past several years is rated for 100V - 240V (or similar) then this will work fine. However, if you have a device that requires 120V (or 100V - 125V) power, using it with this UPS is a very bad idea.
All that being said, if the socket on one UPS works correctly and on another it does not, take it back to the store.

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".
