Welcome to the forum Steve!
You haven't given much info in oorder to help you figure this out.
1. Is it possible the sliders are on a differnt dashboard tab?
2. if you go to the right sidebar in the editor and click the dashboard tab and open all the arrows, what do you see?
#) did you add anything new before this happened?

The 2 images answer the 1st 2 questions.
I had tested the flow that used the Slider on another machine and then imported it into the server that the images are from. Both servers now do not show the Slider, including adding a new slider to a ned flow.
Before the transfer I had updated dashboard on both machines to the latest version no other recent changes.

can you export your flow and attach it to a relpy?
what platform are you running on?
What browser are you using?

Ahhh, you didn't say that the sliders are in a sub flow.
Did you add the sub flow to a regular tab?

I don't believe that you can put dashboard nodes in a subflow, unless I am out of date.

Yup, in the test bed they were not in a sub flow. Will see what happens

Yes, you can put them there, but until you add the subflow to a regular flow they don't show up. What will happen if you add the subflow twice is another thing altogether 🤣

Took copy and deleted before I try and reinstall. Will let you know.

I think that was in answer to my question. Reload the flow rather than reinstall something.
