Hi,
I confirm this is happening when you launch just the default Wavelet Transformation.
Unfortunately the tutorial says nothing about the params used when computing the Continous Wavelet Transform Analyzer.
Have you tried to launch it from under the Analyzers tab, and adjust the input parameters (e.g. make sure the "sample period" is an exact multiple of the TS period as it writes in the tooltip, and play with the other params) ?
Best,
Lia.
