Bug in PCB antenna designer ?

Hello, I'm having a trouble with pcb designer, for example here I'm trying to set Ly as the length shown in the properties of y, which I've done with many others, any tip ? Also I have trouble trouble saving my sessions, if I save it sometimes there will be no save at all and I'll lost my previous work. Thank you for help, Mathias Bedossa.
