sounds like your basket items don't have a identity yet.

> <f:form.hidden property="csvfiles.{file.uid}.contentUid"
> value="{file.contentUid}" />
> <table class="csv-table">
> <thead>
> <f:for each="{file.headerRows}" as="headerrow">
> <f:form.hidden
> property="csvfiles.{file.uid}.headerRows.{headerrow.uid}.rowindex"
> value="{headerrow.rowindex}" />

how does the resulting HTML look like. You're probably missing the 
__identity fields for the child records. If so, just add them manually 
like this:

<f:form.hidden name="csvbasket[csvfiles][{file.uid}][__identity]" 
value="{file.uid}" />

Same goes for any other childs stored in a objectStorage and displayed 
in the form.
