Targa Roof to window seal keep coming out of channel

[sjpgodfrey]

Hi, the seal on the targa roof panel that aligns to the drivers door glass keep falling out in the centre of the channel. Not at either end but in the centre. I have carefully pushed it back into place )one side first then the other side afterwards, but within a mile driving down the road it slips out again.

Am i doing it wrong or is it time for a new rubber seal?

Any advice is welcome and thanks in advance.
