Specific app connect binding no longer working on 4.0

Is this related to Tags split onto several lines in Code View when formatting ?

I am having a similar issue at the moment with this binding

{{(sc_ad_job_q.data.sa_q_job_q.driv_rep_status == null) ? '[Repair Category: not selected in tab 9]' : (sc_menus.data.q_menus.where('menu_list_id', sc_menus.data.q_menus.where('menu_list_id', sc_ad_job_q.data.sa_q_job_q.driv_rep_status, '==')[0].list_ref, '==')[0].list_label)}}

It worked well, without any issues until I upgraded to 4.0.0.

This is what shows on the web page now

The only issue I can see is that the Server Connect Binding won’t allow me to select any part of the Server Action. As you can see, the drop-down arrow is missing.

I am in the process of trying to recreate this Server Action again from scratch. It is fairly complicated so may take me a little while as I am doing it in stages to see if there is any point at which it fails.
