I brimmed my tank before storage and realised the top two bars were missing!! Has anyone had this problem ?
Could the float be punctured?

Don’t fill the tank if storing the bike..
This is the result

Ooh dear.....I thought otherwise, if its submerged surely condensation can't get to the parts.
The tank in the picture was almost full.
But what was the tank in the picture full of? Ethanol absorbs water. I always brim my tanks before the winter lay-up with super unleaded which has a lower ethanol content than regular unleaded. Never had a problem. An empty tank with breathers on a bike in a damp garage (or outdoors) will surely get more moisture in the tank, mainly through condensation as the temperature changes, than one full of petrol. They’re alarming photos but they won’t change my approach.
To answer the OP I’d guess the arm on your float has got bent slightly, probably when the assembly was pulled out/replaced when changing the filter. This would also result in the gauge reading empty with plenty of fuel left in the tank. Just bend it slightly to bring the float down so for a given height of the float it’s reading higher on the gauge. Or don’t worry about it 
Mine doesn’t read full (by one bar) but it doesn’t bother me enough to want to pull the pump/filter out before the filter is next due a change.

I’m not arguing with you. You carry on what’s worked for you.
I only pass on my experiences, the many bikes I’ve had in with the same problems.
The example I posted isn’t a one off, . I’ve posted similar pictures previously.

It could have been stored low previously though maybe.
No way it can get that rust on it submerged surely!!
I was watching Harrys Garage on YouTube his 2024 round up.
He uses synthetic fuel normally, on the one occasion he used E5 Premium from a source that did not get regular turnover it had absorbed moisture to around 10% which wrecked the fuel system on his Porsche, he showed internal parts of the fuel system that had gone rusty as a result the car was off the road nearly all year.
I try and use Esso Premium E5 apparently down south it does not have ethanol in it, I took my tank off my 1100GS yesterday and the internals were bright and shiny with no corrosion at all.
My GS does very little winter riding these days, but I use standard unleaded (10%) and replaced the fuel line u-bend in the tank last summer. Purely preventative as I was going to Europe, but the internals all looked immaculate. It’s stored all its life in a garage though, so I wonder if that’s made any difference.
