Power Fx Container...Issue?

Curious if anyone has come across this, if not, be aware of this unusual behavior.
I have a custom page that is opened from a ribbon button in a model driven app. The single screen is shown.

I have built this custom page using various containers to allow for a responsive design in the event that the end user needs to use various devices to access this page. The Tree View is as follows:

When a user inputs data into each field in a row and clicks the Submit Adjustment button, it collects those records into a Collection named tempTable (for testing purposes only). The following image illustrates the power fx formula showing a simple formula to collect all records where userComments contains some text.

We have filled in two rows. I would expect that only the two rows that we input data into will be collected into the tempTable collection.

However, when we view what is being collected (see image below), we can see that four rows are being collected, but only the last row that we input data into is being collected for each record. This is obviously not correct.

What we found was causing the problem was this horizontal container within the gallery control. It seems to interfere with collecting the correct records and inputs.

When we moved the input controls outside of this horizontal container (and removed the horizontal container altogether), we found that the Power Fx formula ran correctly and as expected. The container seems to cause issues with collecting the appropriate records and inputs. I’ve not seen this behavior before and assume there is either something I have done wrong, or I have found some bug unintentionally.

Anyways....just wanted others to be aware of this unusual behavior so you don't spend time spinning your wheels trying to come to a resolution.
