how to set default Alternateds

[FreedomFoolt]

Sorry, my English is not good.

I use font [SourceHanSansCN-Medium], but there is a problem with single quotation marks [ ' ].

As indicated in the picture:

default Glyph is first one, but it has many spacing, so I use [Alternateds For Selection] choose secend one.

but This is not a permanent solution，I always to choose secend one.

how to set secend one as default Glyph? or eliminate first one's spacing?

Thanks in advance.
