My toilet seal has seemed to have swelled and I can’t get it to close. Has anyone else experienced this or am I doing something wrong?

Thanks everyone for your advice. I have taken the seal out but it still won’t close. Pausim may have the answer as I use WD40 to lubricate thinking it was silicone based. Will buy a new seal and use Thetfords lubricant.Has the seal come adrift? That might make it bulge. I would replace the seal, there are Youtube videos on how to do this and it looks fairly easy.
Edit.
ps WD40 and similar are known to damage plastics and rubber so avoid these and only use approved lubricants.
I just replaced the seal in our Thetford C260 with this https://www.amazon.co.uk/dp/B0B48X6YNX?tag=mhf04-21Thanks everyone for your advice. I have taken the seal out but it still won’t close.
