Swing left on bug with waveform

With swing button left on, then push A button to edit and see waveform , then tap pad associated with waveform, it disappears back to swing page with vertical waveform line appearing, not a show stopper , just hit back button to pattern page and press A button to return to waveform, it doesn’t seem to do this while in other top button modes,
Hope I have explained this ok?

Very clear explanation. Thanks. Fixed in dev. Will be in next update.
