There is possibly a bug, which I am yet to work Around.
I changed the method used in the set statements and and the bug is now more
evident
<$set name=person-tiddler filter="[<row>splitbefore[:]removesuffix[:]]" >
<$set name=first-name filter="[[$row$]split[,]nth[2]]" >
The first person-tiddler value is always
[[first surname]]
the first time
then ALL subsequent rows it is
[[ firstsurname]]
where a mysterious space is inserted in the result.
In my previous set statements using {{{ filter }}} this space seems to have
caused a failure of sorts
Using the
filter="[<row>splitbefore[:]removesuffix[:]]"
Now shows the unwanted space
Perplexed
