Add Row Link Working when Testing Interface but not in Record List Action

Hi,

I have several editable grids in my interface with an add row link. When I'm testing the interface in the rule editor, the link works just fine for all grids, but when I try to create a new record using the record list action, clicking the link does not do anything. 

The grids are implemented as follows:

a!gridLayout(
label: "Wachstumstreiber und Schlüsselerfolgsfaktoren",
labelPosition: "ABOVE",
emptyGridMessage: "Keine Wachstumstreiber angegeben",
headerCells: {
a!gridLayoutHeaderCell(label: "Wachstumstreiber"),
a!gridLayoutHeaderCell(label: "Schlüsselerfolgsfaktoren"),
if(
local!readOnly,
{},
{ a!gridLayoutHeaderCell(label: "") }
)
},
columnConfigs: {
a!gridLayoutColumnConfig(weight: 1),
a!gridLayoutColumnConfig(weight: 1),
if(
local!readOnly,
{},
{ a!gridLayoutColumnConfig(width: "ICON") }
)
},
rows: a!forEach(
items: ri!konzeptRecord['recordType!{e6823cb0-0826-4ba1-a489-d1b628fb0037}PEP Konzept.relationships.{6913d9a7-ad1d-43c7-b38b-1b504c3122bb}wachstumstreiber'],

The rule input ri!konzeptRecord, into which the rows are meant to be saved, is passed down using the following call in the parent interface being used for the record list action:

rule!PEP_KonzeptMarktanalyse(
konzeptRecord: ri!konzeptRecord,
readOnly: ri!readOnly
),

I'd be happy for any pointers, as I find the inconsistent behavior between rule editor and actual call of the record list action very confusing.
