Saved question not showing up when trying to add a series to a graph

When trying to add a series to my graph in a Dashboard, a lot of questions doesn't show up when searching. I can easily find it when searching for it regularly or by browsing. The series I'm trying to add is a saved question that is identical, but with other filters. See the screenshots:

Reproduce steps:

  1. Enter edit mode on Dashboard
  2. Click "Add series" on the graph in question
  3. Search for the question you want to add
  4. Conclude it's not showing up.

Not showing up

Showing up with regular search (have blocked some parts of the screenshot out):

Update: After a couple of days, some new questions are showing up in the Add Series, but not the ones i actually need. I've tried bookmarking, deleting, re-creating to force it to show up, but with no success.

This is very frustating!

the questions that we show are the compatible ones. I would suggest you check that the questions have the same y-axis. Also, we're upgrading massively this modal on v47, so stay tuned

It's the same question with another filter, every part of the question is duplicated and completely identical.

I really hope v47 fixes this.

I experience the same issue in version 46.6.4. The suggested series to add did show in version 44 and earlier. So something has stopped working between version 45-46.
