After the plugin update, cannot edit shortdoce tables

I noticed that the size chart plugin has a redeveloped chart design feature. The charts I have created before are displaying but I cannot edit them. I only place the chart by placing the shortcode. 

I tried to edit one of the charts by the design-customise but  I cannot see the chart table and once I published my edits (I changed only border thickness) this chart was replaced by another one. You can see it on this page: https://wilda.eco/shopping-guide/#size-guide – please click measuring for blazers and there are tabs with metric and imperial. size charts The Blazer Imperial Chart was replaced by Size Conversion Chart ( whereas it should be same as Blazer Metric chart but with imperial measurements).

Can you help me to enable editing my current charts without destroying them and reverse the Blazer Imperial EN table weird change?

I have contacted you support via email but have not got any reply.
