TOPIC: display of several buy buttons on one Joomla page

Hello
I am trying to display more than one item for sale on a Joomla page.
Only one display for some reason. The second one shown below never shows.

Here is the code
<p> </p>
<p>First</p>
<p>{quicksell file="Tribeca Pool Units List.pdf" price="2.00" title="First" currency="" customPayPal="" emailDelivery="" requireRegistration="" discount_rate="" return_url="" notification_email="" rm="" cbt="" sub="" addToCart="on" partner_id="" license_id="" freeForGroup="" assignUserToGroup="" subscriptionEnable="" subscriptionRate="" subscriptionBillingCycle="1" subscriptionBillingCycleUnit="M" subscriptionRecurringPayments="" subscriptionRecurringTimes="" cbpl="" bundleSelect=""}css_buttons/purefin{/quicksell}</p>
<p> </p>
<p>Test purchase ($0.00) </p>
<p>{quicksell file="JSitemap_Professional_Documentation (5).pdf" price="1.00 " title="Second" currency="" customPayPal="" emailDelivery="" requireRegistration="" discount_rate="" return_url="" notification_email="" rm="" cbt="" sub="" addToCart="on" partner_id="" license_id="" freeForGroup="" assignUserToGroup="" subscriptionEnable="" subscriptionRate="" subscriptionBillingCycle="1" subscriptionBillingCycleUnit="M" subscriptionRecurringPayments="" subscriptionRecurringTimes="" cbpl="" bundleSelect=""}css_buttons/purefin{/quicksell}</p>
<p>that all </p>
<p> </p>
