Steps to reproduce:

1. Use a template with lot of items (>1500 in my situation) like a template for switch arista by SNMP
2. Look subfilter without any filter like screen image-2024-04-30-15-50-10-940.png
   1. Subfilter component:storage count 6 items
   2. Blur is for hidden the interface's description
3. Now if you use filter Tags like screen: image-2024-04-30-15-46-24-064.png
   1. you can see the real number of item with tag component:storage

Result:

Bad result with subfilter: image-2024-04-30-15-50-10-940.png

Good result with tags filter: image-2024-04-30-15-46-24-064.png

maybe the high number of tags must be at the root of this behavior ?
