Small annoyance: typing three double quoted strings in scala results in six double quotes

I am trying to use string interpolation.  Recently (uncertain precisely which IJ version..) when typing  s"""Some interpolated string""",  as soon as I type the third double quote after the initial 's' then four more double quotes are added -for a total of six.

This appears to be a bug, but then maybe there is a setting to disable the "smart" (but actually incorrect..) double quoting?

**UPDATE** I found a setting that would have seemed to be the appropriate one "Insert pair quote":  but it  does not work (I have it unchecked but still the 'paired' quotes are inserted). Well, "paired" in this case means "three more when you type in three"
