Description
An issue with lnd results in duplicate entries in the on chain transaction list.
This results in metric collection failure as multiple series with the same labels are created.
Error:
An error has occurred while serving metrics:
collected metric "lnd_tx_num_confs" { label:<name:"tx_hash" value:"xxxx" > counter:<value:11894 > } was collected before with the same name and label values
