Tub surround flexes causing caulk to crack..is this normal?

I think our the tub surround abover our bathtub move too much when we lightly press it. Not sure if this a poor installation job by the previous owner or if I just need more caulk. Read on!
We moved into a 58 year old house and the caulk in the tub between the tub and the walls (where were plastic ..not tile) was partially moldy so we took it out and redid it using DAP bathtub caulk. We let it dry (as we were not living in the house for 2 weeks) before and after we caulked. The first night we took a shower and lightly pressed our hand on the wall, the caulk cracked. I figured I did not put enough caulk on, so I did it again and dried it very well. However, the cracks continue. I think the problem is that the walls above the tub (called a tub surround from what I can guss, as they are not tile but some sort of plastic) has two joints that seriously depress when you even lightly touch them. Is this amount of give normal? I have never had a tub surround above a tub so I am not sure what to expect. How much give is normal? Any solutions?

I suspect that there are some problems behind this surround that need attention. Best ideas is to remove this surround and replace it with something more solid (firm).

I can't tell you if the current surround will be able to be reused and in my opinion I would replace it. Check out Lasco or other similar products that will do the job.

I stress that any surround (adhesive applied type) will require a good sound backer (substrate) so inspect what is there and replace if required. I would suggest replacement just the same.

Good Luck!
