Hi @AndrewSy
Ok then what you need to do is Filter the actual Choice Column (not use the Choice).
What I mean is. Lets say you have a table and one of the columns is a value FROM this Choice.
And each row is assigned to a user
What you want is to Filter that Table, by whatever column you can filter using that persons info, then use the Choice Column itself to build a Unique (Distinct) list of Choices that has been used by that person AKA Projects.
What you are doing is simply using the Choice as a "thing" to list the total possible project selections, your not actually working on this persons lists of SELECTED choice values (aka projects).
Since its 2am I am going to share this versus typing more. Feel free to response and I will look at it later
