2 Ideas.

 

1. Choose some transform operations on the transform columns menu, e.g. "Trim"(in the "Format" group) and adjust the generated code.

 

let
    Source = CurrentTable,
    #"Splitted Text" = Table.TransformColumns(Source,{{"Topic", each Text.Split(_,";"), type {text}}}),
    #"Expanded Topic" = Table.ExpandListColumn(#"Splitted Text", "Topic")
in
    #"Expanded Topic"

 

2. Use split column with advanced option Split into rows. Resulting code (no adjustment required):

 

let
    Source = CurrentTable,
    #"Split Column by Delimiter" = Table.ExpandListColumn(Table.TransformColumns(Source, {{"Topic", Splitter.SplitTextByDelimiter(";", QuoteStyle.Csv), let itemType = (type nullable text) meta [Serialized.Text = true] in type {itemType}}}), "Topic"),
    #"Changed Type" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Topic", type text}})
in
    #"Changed Type"
