What wood filler do I need?

[OM2]

A kitchen drawer fell down.
I had some special wood filler - 2 materials you rub together.
I used and filled.
Normally the filling goes solid rock hard.
But I don't think I got the mixing right (or it's sooo old)... the filling is soft.

Now... just wondering what I do? Scoop out and refill?
What filler should I use?

See pic of what is was before I filled below:

Thanks.

Use the other holes in the runner, if there aren’t any drill some.

I'll have to drill though the metal.
But... if that does the job... I'll try that.
Thanks.
