Query: Water dissapears!!!

At first this seemed to be the perfect tub. The 'ramp' offered just the right support to hold my daughter while bathing. Then it came time to extend the tub. This is when the problems began...... Every night I would fill the tub, once it is full I would go to the nursery to undress my daughter and get her ready for her bath. We would return to the bathroom to find the tub almost empty! At first I thought the drainer was left half-opened. Turns out that the water was draining from the bottom of the tub at the seam (where you extend the tub). I tried re-securing the seam by pulling on the sides and pressing on the latches at the bottom but this did not work. Oh, with regard to the supporting ramp, it does not lock in place. When my daughter moved, it would push the rap upward causing my daughter to get deeper into the water; in addition, no matter how much I hung it to dry it would still have a very distinctive "moldy" smell. What a dissapointment.
