Hi, note this is not unique to Alertmanager YAML editor, I see the same behavior under Pods -> Pod Details -> YAML. Please see attached image.  I believe the Monaco editor might be showing error/info tips for every error it finds in the YAML block(?).

We will look into this in the next sprint.

Comment 9 David Taylor 2020-09-28 16:11:45 UTC 
The latest stying of the YAML Editor clearly shows hover selection range via the semi-transparent light blue highlight/background. When moving the cursor the hover selection switches between single and multiple line 'hover selection'.  When the hover selection range covers a block of yaml it shows all warnings within that range -even if they are duplicates.  This may be giving the appearance of duplicate warnings in the tooltips.

Please see attachment 1717288 [details]

Note moving the cursor over just one character to left, changes the hover position/selection to just encompass a single line.  This limits the warnings to just a single warning.
