Wavetable editor locks out wavetable

I load a wavetable with a sequrence of wave forms. I can sweep through them by using an LFO. But if I do any “edits,” like altering harmonics on a waveform, the usable wavetable is then limited to that single wave, and the rest of the waveforms are gone from the sweep and from the 3D oscillator view. How do I access the whole wavetable again?
