Rated 4 out of 5 stars

First of all, I'd like to congratulate for this very useful addon.
However, lately I have noticed a trouble that happens only for a particular sender.
I've been looking for similar problem on forums, but I never found.
- My problem :
Reply does not use the template it should, it uses none, though Create and Forward work well.
These senders have an automated disclaimer added by their mail server whether in HTML format or in TXT. When I reply to a TXT disclaimer mail it works. It does not when HTML.
It used to work well. It happens on Thunderbird for MacOSX and for Ubuntu.
- My config :
Ubuntu 16.04.4, Thunderbird 52.6 (64bits), Stationery

Any help would be appreciated.
