Luna G3 humifier water chamber - design change or wrong part

[ldt2g10]

good afternoon,

I recently purched some humidifer water chambers for my lunch G3.

I'm a little confused as the new chambers, although they fit, do not look the same as the old ones.

Was there a design change on these? Or was I sent the wrong part?

It's mostly just the top Part that looks a little different. I'd add an image but the file is too large

I hope soneone can help me solve this little mystery.
