Non-recurring payments

Newbie here, your help will be greatly appreciated.

In general, lm_paypal_subscriptions is working just fine for me EXCEPT for one show-stopping problem.

I created a subscription with "recurring payments" unchecked.
However, after the user signs up for a subscription, he receives a message from Paypal, falsely indicating that payments are recurring:

You have successfully signed up for a subscription to xxx
using PayPal.

Your first subscription payment, for $5.05 USD, has already been sent
to xxx.

----------------------------------------------------------------
Notification Preferences
----------------------------------------------------------------

Your Email Notification Preferences are currently set so that you will
not receive an email receipt each time a payment is sent for this
subscription. If you would like to receive an email receipt each time
payment is sent for this subscription, log in to your PayPal account and go
to the "Profile" subtab of the "My Account" tab. Choose the
"Notifications" link from the "Account Information" section and follow the
on-screen instructions to change this Preference.

----------------------------------------------------------------
Cancelling Your Subscription
----------------------------------------------------------------

If you would like to cancel this subscription, log in to your PayPal
account and go to the "History" subtab of the "My Account" tab. Choose
"Subscriptions" from the pull-down "Show" menu and press the "Submit"
button. Choose this subscription, and click on its "Details" link. You
will be taken to a Transaction Details page from which you may cancel your
subscription. Cancelling your subscription will immediately stop all
future scheduled payments for this subscription.

Please, I cannot go live until this problem is addressed. Though I am not using recurring payments, I would like to take advantage of other functionality in lm_paypal_subscribe such as expiration notices.

I posted a similar support request about a month ago, asking for advice on how to create a hybrid between lm_paypal_subscribe and lm_paypal_donate, so that I could take advantage of eg expiration notices, without the side effects related to recurring payments.

I don't if a hybrid is the best approach. Any advice on how I might bypass the specific problem described above, where paypal sends the customer a misleading email, would be most greatly appreciated.

I have put many hours into get everything up and running just so, and would hate to give up on lm_paypal when I am so close.

Thank you.
