Solved. thank you
I mistook Shift + Select as selecting two tags.

Selection tag in Property Inspector: This issue was addressed by pressing Shift + Select button.

Hello Dr. Sassi

Happy New Year

Same problem as above,
but there is a symptom that only one is selected even if the selection tag is selected together.

It doesn't work in 2023.2.2 and 2024.5 versions.
Is it a bug that works when updated?

I'll share a test video. https://youtu.be/q-FA1BOAiUg
