No Activation_link and Forgot_password TAGS in user email advance settings

Thank you for your great work.
I have the usersWP in my geodirectory and while some of the mails work others don’t.
1. From advance user email settings both activation and forgot password link tags aren’t there and instead the login_link is put in the mail content. As a result, registration and forgot password emails sent to users lack the activation link and password reset link respectively and instead both mails only include login_link which thwarts their effort to activate their account or change password successfully.
I attempted using the [activation_link] and [uwp_forgot] shortcodes I got from some responses in earlier similar queries here but instead they didn’t work and only appeared as an inactive link on sent mails e.g “Please click this link ‘uwp_activate=yes&key=inSlKs5juSLAzGt5bRza&login=Kinjo1’ to activate you account”
2. Another problem discovered was after several attempts to resend the forgot password mail, the users could no longer receive any of users WP emails. Even attempts to register new users failed sending registration/activation mails. I later deactivated and reactivated the usersWP plugin and it worked for new members (receiving emails but still without activation link)but older members do not receive any userswp emails despite even re-sending from backend.
Based on explanations above:
1. Why doesn’t my plugin have the Activation link tag and change password tag? I assume this is why emails sent in both cases only have the login link which instead redirects users to account/login page yet they simply need to change password or have account activated. Is there a usersWP version with these tags? I have 1.1.3.
2. Why aren’t users receiving mails altogether..although I guess it could be cause I sent many forgot password emails while trying to see if it work effectively. But even after deactivating and activating again the old user with forgot password issue still can’t receive any of userswp emails even after using the resend button in backend.

Thank you for your help.
