Please could you share a snapshot of the model and the tool dialog which shows the issue mentioned above? Alternatively you could share a toolbox with the model as well. This will help us replicate the issue. Pls also share the ArcGIS Pro version that you see this issue.&nbsp;<BR /><BR />Thank you!</P> Fri, 03 Apr 2026 07:34:55 GMT https://community.esri.com/t5/modelbuilder-questions/model-builder-tool-forgets-looses-settings/m-p/1694328#M4149 ShitijMehta 2026-04-03T07:34:55Z
