One batch, two pints, two different outcomes...

[SwiftG40]

So last night I poured my first Homebrew pint. It is a 5gal batch of Wherry Bitter, I bottled half & kegged the other half & had no problems during the whole process. Now last nights pint out of the keg was really nice, malt with a nice bitter after taste, a really good head and light/medium carbonation. A winner I thought...
Tonight I opened the first bottle & it just came out like fizzy cordial, no head whatsoever, not the same malt taste & a bit over carbonated for a bitter. I put 1/2 teaspoon of dextrose per 500ml bottle & the equivalent in the keg (2 1/4 gal)
I've been reading all night about possible causes which I can understand but I can't understand how this has happened to two pints of the same beer from the same batch.
The only things I can think is the first pint glass was dry out the cupboard & tonight's glass came straight out the dishwasher which I then rinsed. Other than that I'm puzzled, see photos below of what I mean

Sorry about the long post...

Does the bottled one taste carbonated? How long was it in the bottle?

Do you happen to use a rinse aid in your dishwasher? I've read that they'll leave a film on things that kills the head retention. That is one thought.

Yeah the bottled one is carbonated (even though it doesn't look it, it had the kind of fizz a medium lager would have), too much for a bitter really. I bottled & kegged on Jan 10th (Primary was definitely finished too). I'm wondering whether it just need longer to condition? Maybe give the bottles a little shake & rest for a few weeks?

Yes I do have rinse aid, next time I will make sure I give the glass a good thorough clean with fresh water first. It came out of the bottle like it looks in the picture though so a head didn't even get a chance to form

I've had the rinse aid problem but it was not that noticeable.
