Track edition impossible

The application runs well and recognizes the CD which I tried (a French one) but the local characters and accents are not properly loaded. I wanted to correct them specifically but the Edit features is not available for the track names ! While other elements can be corrected (and not always as critical as the track names...). So I cant use it properly, a bit disappointed. No current plan from the editor to correct this, despite my demand to their support.
