Update nested mirror columns

I extensively use Monday like a database with many to one relationships between boards. However, there is an update issue with this if a mirrored column is in itself a mirrored column on another board. (ie nested)

When opening the board, the data does not update (just remains blank) unless:
a) the intermediate board is opened first in the same browser window
b) the Linked item is clicked on the board

Neither of these work around options are fit for purpose when you are dealing with staff who are “finding it difficult” to make a change to their working methods!
I want to set up filters on the board, but the filter simply does not work when the data is blank.

Are there any other work-arounds for this bug?
How do I report this as a bug?

Following this- as I use it as well, and was told mirror columns cant be nested for now.
