oh, i think i worked out how to fix my issue. clicked my merged patch, went to apply script/list records referencing specific plugin and pointed it at the plugin i needed to remove. it spat out two records that needed to be removed, so i removed them from the merge patch and then went to the header and hit the clear master button. seems to have removed the two records (a change to an outfit name and i think some added item to a chest in solitude) and has also removed the merged armor plugin as a master.
