Some terms in modelling are overloaded...
Entity is one of them... However, EA only has one definition - that of a Jacobson Analysis type. Hence if you stereotype a class «entity», you will, if the
Tools|Options|Objects|[X] Classes honor analysis stereotypes is marked, get the familiar Circle and Line underneath image (Shape script?).
However, an entity is also the logical/conceptual version of a table (as in ERA - Entity Relationship Attribute modelling).
If you don't want the Analysis image, for some diagrams, but you do for others (because in your repository you have BOTH types of entities) you're stuck.
These kinds of settings need (as I have often remarked) to be at the Repository, Diagram and Element level.
As it happens, for our particular circumstance, the data modelling entity is never alone, it is always an auxiliary stereotype (because EA doesn't support Data Modleling elements as separate element types - such as Requirements, Issues, Screen etc - but as stereotyped classes). However, if the above checkbox is marked, the image override comes into play regardless... However, with the «table» stereotype this is not the case!

EAUI!
