Spring Cloud Sleuth Traces w/ Gradle not showing up in Zipkin - spring-cloud-sleuth

Question

I have a Spring Cloud Sleuth + Stream app working and sending to my local OpenZipkin (docker) when the app uses maven, however when I try to run an gradle spring boot app then Zipkin doesn't display the traces. The interesting thing is that the Spring logs seem to show the proper trace information..so the app itself is recognizing Sleuth but for some reason Zipkin either isn't receiving the info or it's not displaying. I went into the zipkin container and can't find any logs. How can this be troubleshot? Is there something that needs to be set when using gradle that isn't needed with maven?
Config info:
In the build.gradle file I have included sleuth as so:
implementation 'org.springframework.cloud:spring-cloud-starter-sleuth'
Version info:
set('springCloudVersion', "2020.0.4")
id 'org.springframework.boot' version '2.5.4'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
The only thing I am configuring in my application.yaml is below and it's the same in both the gradle and maven app. So I'm not pointing to some other address for zipkin or anything like that:
spring:
application:
name: OrchestratorService
sleuth:
sampler:
probability: 1.0
And app logs recognize Sleuth and include the app name, and trace info in each log entry, for example:
[2m2021-10-06 10:42:22.508[0;39m [32m INFO [OrchestratorService,9b22b40072a8931c,3f954b3ab81e4e7d][0;39m [35m21261[0;39m [2m---[0;39m [2m[pool-6-thread-1][0;39m [36ms.s.d.f.O.OrchestratorServiceApplication[0;39m [2m:[0;39m No further outbound event for card block service required.

Please do as the docs says:
Use spring-cloud-starter-sleuth which should add Sleuth support with log correlation and spring-cloud-sleuth-zipkin if you also want to send spans to Zipkin.
Here's an example from the docs: https://docs.spring.io/spring-cloud-sleuth/docs/current/reference/htmlsingle/#how-to-set-up-sleuth-with-brave-zipkin-http
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${releaseTrainVersion}"
}
}
dependencies {
implementation "org.springframework.cloud:spring-cloud-starter-sleuth"
implementation "org.springframework.cloud:spring-cloud-sleuth-zipkin"
}
