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?
