Tips for Working with Picklist and Multi-Select Picklist Formula Fields
I have seen similar issues and below is an example where R&D has provided the following resolution. Posting it here for your reference
Resolution: R&D found that several roll-up summary/formula fields were actually pointing to a previous field product_family_old_c. In order to fix this issue, we need to have customers go to the "Where is it used?" button on the Product_Family_c field on the Order Product object. From there they need to navigate to all the custom field references and edit those fields, force recalculate any roll-up summary fields and then save. This ultimately resolved the issue.
If you are unable to identify the issue, I recommend raising a support case
