Titebond issues

[Evaradero]

Recently i made a 10 g vert with a titebond and tree fern fiber background. All went well, i planted the viv and started let everything grow in. But once the tank got humid, all the titebond seems to have been rehydrated and the viv smells of titebond. I opened the viv and put a fan infront of it for 3 days, and it was fine, then the titebond small came back. Any ideas?
