<$set name="last" filter="[{!!title}removeprefix[jingle ]]"
select="0"><<last>></$set>
When assigning the value of a set widget via a filter, it is important to
note that the value is a title list and not a title.
In a title list, tiddler titles with spaces are enclosed in double brackets.

Please see the section Filtered List Variable Assignment
Filtered List Variable Assignment
This form of the set variable widget evaluates the filter and assigns the
result to the variable as a space-separated list (using double square
brackets for titles containing spaces).
<$set name="myVariable" filter="[tag[HelloThere]]"> <$text
text=<<myVariable>>/> </$set>Filtered Item Variable Assignment
NEW IN: 5.1.14 This form of the set variable widget evaluates the filter
and assigns the specified result to the variable as a single item (ie, not
using double square brackets for titles containing spaces).
<$set name="myVariable" filter="[tag[HelloThere]]" select="0"> <$text
text=<<myVariable>>/> </$set>
