admin side issues LeadForm plugin

Hi I am happy of NoveLight and thought to be also of this LeadForm plugin. But there is a big issue. On the admin panel leads can’t be open to be read. They show up only in preview.
Here down I copied and pasted a mail from another user (who left the plugin btw) because these down are my same issues.
PLEASE HELP

(1) When I change the settings to ‘receive the new lead in email’, I get the message indeed in my mailbox (although in a rather rough form, but I don’t suppose that can be changed), but from the user’s viewpoint it is not clear that the message has even been sent, because not only is there no message showing e.g. ‘Thank for for submitting the form’ but also the form does not even clear up, ie the page does not refresh anew.

(2) If I then choose the option to ‘save the leads on database’, then from a user’s perspective they do get a message saying ‘Thank you for submitting’ and the page gets refreshed and the form cleared up. However when I go on the admin section and check the list of the leads, there is no possibility to upload or read the full message if it is longer than 2 words. Is there a solution to that??
