Possible bug in Data Table editor

I have a Data Table that uses a USTRUCT defined in C++ as a template. That USTRUCT (let’s call it StructA) contains a TArray of another USTRUCT (let’s call it StructB). StructB has an FString property that I need to be multi-line. That property is marked with “meta = (MultiLine = true)”. However, when I try to edit this property in the Data Table editor, it will not allow me to insert line-breaks (Shift+Enter). As a test, I used StructB alone as a primary template for another Data Table and, in that case, I can insert line-breaks.
This seems like to a bug to me, but I wanted to get some feedback before I reported it. FYI I’m using Unreal version 5.4.4.
