Missing instances in Time Series Insights UI

Hello,

When we view our instances in TSI Explorer we usually see the following result:
163549-allassetsshowing.png


Which shows us that there are 8 instances for ABB which is correct. However sometimes we see the following:

163578-oneassetshowing.png

Suddenly we have lost 7 instances for ABB and if you look closely to the top level (Kenter assets) you can see that that has gone down from 447 to 429 as well. If we then go to the model page we are indeed unable to find those instances. However if we download the instances using the button in the UI we get a JSON which does contain the missing instances. Likewise if we query the time series API we do get the data for the missing instances.

We have only seen this behavior with recently added instances and it's always happening with the same ones.

So to me it seems it's just a visualization problem in the UI. I just don't understand why it's happening and why only on an intermittent basis.

Any help to fix this issue would be greatly appreciated,

Menno

@MennoDolstra-8911 Welcome to Microsoft Q&A forum!

You have mentioned, "We have only seen this behavior with recently added instances and it's always happening with the same ones" What type of instances are these?

Do the instances show up after some time?

@AshokPeddakotla-MSFT
Yes the instances show up but then disappear again, a while later show up again, etc. I'm sorry i didn't mean to say it was happening to a certain type of instance just that we only see this behavior with recently added instances never with older ones. Currently we have 447 instances but it jumps back to 429 when the issues occurs. When we had 440 it also jumped back to 429
