magento2.3 – Some admin users can not see all the products

We have come across a strange issue.

We are 3 people with admin privileges in our Magento admin site.

When we search for a specific SKU in filter, 2 of us get the same result and 1 get a totally different result.

2 of us get 2600 records and we can go to the next page etc, but the last one he only gets 1 record found but is showing 999 records but are not able to go to next page. When i uses the tick boxes on the left side to tick 1 box then all the boxes gets ticked.

We have made sure that we are using the same filters etc.

Anyone that had the same issue knows how to fix this?

thanks.
