sram front derailleur issue

I have just replaced a broken sram front derailleur (x4) with a newer one(x5). My issue is that the new derailleur has to be fixed in a way that the outer plate of the cage is quite a lot higher than the biggest front cog, all the videos that i have watched on youtube(park tool,gcn etc) tell me that the outer cage should be within a few mm's above the biggest cog. If i do this the inner part of the cage touches the middle front cog and stalls the motion, the inner cage plate is a lot lower than the outer cage plate. Does it matter? Is this something particular to sram? Some advice would be much appreciated. I hope i have explained myself well, if not i can add more information. Thanks.

A pic would good. If its not possible to have it that low it will still work higher. What model is it?

Its an sram x5 low front derailleur(3x9). It shifts ok but im just worried about the chain coming off the top ring. I have replaced sram with sram but now im wondering if i should have just bought a cheap one from decathlon which i think is microshift. I'll try and get a pic up. Cheers for the reply.

, the inner cage plate is a lot lower than the outer cage plate.
I think this is your answer, the 2-3 mm guidance is when the inner and outer cage are at similar depths. I’ve not seen an X5 FD, but sounds like it’s a tad different. If it shifts OK then it is OK.

This is how it looks, Its how low the inner cage plate is compared to the outer which is making me set it higher.

I can't really see what is preventing it from going lower from that pic. The chain stay would also present problems if going lower.
I had to file out a chunk on my Microshift FD as a bottle mont braze was in the way.

From the other side, the inner cage plate has the minimal amount of clearance over the middle cog of the front three

I'm pretty sure its a triple, this(pricier) sram one is pretty much identical and its a 3x10. Maybe its a new design or maybe im not understanding the difference between double and triple?

Yeah I actually ordered the high clamp from tredz, it took three weeks to come and they sent me the low clamp instead. I assumed the cage would be the same on both, maybe im wrong, I have not seen a picture of the high clamp. This has turned into a bit of a goosechase tbh, should have gone to my local bike shop. The derailleur shifts ok but just looks a bit odd, if the chain starts coming off I'll change it.
