Is the new one a 2-gang switch? The wiring diagram you posted seems to suggest that it's a 2-gang 2-way switch, and not an intermediate switch of any sort.
The one that links the Common of the first two way with the Common of the second two way, normally housed in the backbox of the intermediate switch. You can see it in the picture.

The way I see this 'intermediate?' switch by retrotouch incorporates the Com link (terminal block) into the switch itself therefore doing away with the need for a terminal block.
Or am I missing something here - or is a large drink and a dark room needed.
Apologies - it seems I wasn't paying enough attention and conflated the make "Retrotouch" with the touch models.
However that diagram is clearly not that of either a Retrotouch intermediate rocker switch:
or a Retrotouch touch switch:
And as for the back of the switch in your photo being the terminals for a 1-gang intermediate, do you know what they have done? They have taken a 2-gang 2-way and fitted a wide rocker to it so that both gangs work together, and they tell you to wire it with the L1/L2 cross-links as shown so that it mimics the behaviour of a 1-gang intermediate.
Words fail me.
But then this tells us a lot:
It tells us that it was made by someone who doesn't really know what's required, or doesn't care if it means he can drive down manufacturing costs.
It tells us that it was probably made by someone who doesn't care about safety.
And the lack of a CE mark tells us that it should not be on sale in this country.
I would imagine in your situation you ignore the Com and just connect the L1 1 (old L1 in) and L1 2(old L2 out) and L2 1(old L3 in) and L2 2 (old L4 out).

No - what you need is to draw a 2-gang 2-way switch, with L1A linked to L2B and vice versa, your two "incoming" conductors going to the COMs, and see how it behaves when you operate both gangs together.
I haven't come across that type of switch before, but I would imagine in your situation you ignore the Com and just connect the L1 1 (old L1 in) and L1 2(old L2 out) and L2 1(old L3 in) and L2 2 (old L4 out).
