Strange character macros pop up in Macro bar

Hi all I have a PRO licence During my Cthulhu game tonight I have found that in the Macro bar (GM) 2 new macro buttons have popped up that I have not created. They are only visible for the GM, not the players.  Those 2 macros are not listed in the Collection list.  In fact, according to the naming, they are associated to 2 NPCs (Erkin and Li Hue) Tha names displayed in the buttons are Erkin: Additional skill 3 and Li Hue: Additional skill 2 I have not created any macro associated to those undefined skills.  I have then opened the NPC character sheet assuming that for whatever reason the macros would be defined in Attributes & Abilities.... but they are not there. So I have no clue how those 2 useless macros have been created (undefined skill rolls). And I do not know how to delete them as they are nowhere to be seen in any configuration I am really puzzled. Anyone has any idea I can try? (Today the platform was not working smoothly, by the way. And for whatever reason all NPCs and characters sheet had their HP and Sanity stats were blank. Coincidentally those are the 2 stats that were displayed in the tokens attributes. The values were visible in the token, but the stats were blank in the character sheets) Thank you in advance for your comments

Hi Whurn H.,  Hover over the button, on the right hand side a handle will appear. Grab the handle and pull it upwards towards the top of the screen, then let go. That will remove the button no matter what the source is. 

Thank you: I will try (the second issue I mentioned of vanishing HP and SAN  is solved: it seems I did not properly realized how does linking a token and a character really works…9
