I don't know of Token does the space of path auto.
I use [node:field-site-section-basic-page:root] the root of taxonomy .

I triple checked that there is no space in front the taxonomy term
I triple checked that there is no space in front of the the pattern
I triple checked value directly in database no space in front of the value.

the tax is selected by dropdown menu, so no user input.
I hope it gets resolved soon or something can do to fix it.

Check if there is any special character in the front of your [node:field-site-section-basic-page:root] token. As far as I know %09 is equal to "horizontal tab". You may not see it on screen. Try copy to plain text box and copy it back to the field.

same problem with standard token [term:parent:name]

pattern [term:parent:name]/[term:name]
return:

%09/term1 - for parrent terms
%09term1/term11 - for child terms
