[Qgis-user] Help with Buffer and Category-Specific Geometry Outputs in QGIS

Hello everyone,
I'm using QGIS 3.34 and working with the vector-geometry-buffer function on a shapefile containing multiple spatial points, categories (or location type) are represented as a group of these spatial points. For each category, my goal is to calculate the geometries (perimeter and area) created by the buffers.
While the output result includes these geometries, it does not properly associate them with their respective categories. Instead, for each row in the output, I see the same category listed but with varying perimeters and areas, making it difficult to distinguish which geometries belong to which category.
Example
input file_(here I use column APA_radius as variable distances for buffer)
[cid:758816fb-ea5b-411d-8cc1-30dc566b1186]
output file_9as you can see geometries for both categories but no idea which geometries belong to which category)
[cid:c6279fc3-a799-4223-b47d-d5a9d61261e3]
Has anyone encountered this issue before? Is there a specific step or method I might be missing to properly link the geometries to their respective categories?
Cheers & Happy Holydays!!
