i have burned 20 000 xch in clearwallet.io with the primary adress.

i want to burn more xch so i created a new adress in the same clearwallet account. it was working, i was able to burn 8700 xch yesterday with the secondary adress.

but today when i want burn 3200xch more with the same secondary adress, i get "You have already converted the maximum allowed VIA from this address."

i don't understand where i'm wrong? I thought that two adress in the same clearwallet account were possible.
