Ehcache 2.10.6 hit statistic not being incremented

I've set up a cache in one of my projects, along with the custom health indicator as below:

@Component
public class CustomHealthIndicator extends AbstractHealthIndicator
{

    @Override
    protected void doHealthCheck(Health.Builder builder)
    {
        CacheManager cacheManagerInstance = CacheManager.getInstance();
        Ehcache cache = cacheManagerInstance.getCache("myCache");

        builder.up()
                .withDetail("Cache Size", cache.getSize())
                .withDetail("Cache Hit Count", cache.getStatistics().cacheHitCount())
                .withDetail("Cache Miss Count", cache.getStatistics().cacheMissCount())
                .withDetail("Cache Put Count", cache.getStatistics().cachePutCount())
                .withDetail("Cache Remove Count", cache.getStatistics().cacheRemoveCount())
                .withDetail("Cache Expired Count", cache.getStatistics().cacheExpiredCount());
    }

When I run it locally and go to localhost:8080/actuator/health all the other statistics update but the hits doesn't.

{"status":"UP","details":{"Cache Size":9,"Cache Hit Count":0,"Cache Miss Count":9,"Cache Put Count":9,"Cache Remove Count":0,"Cache Expired Count":0}}

My code accessing the cache in my other project is:

Cacheable cachedResult = CacheManager.getInstance().getCache(request);
if (cachedResult != null)
{
    CustomResponse response = (CustomResponse) cachedResult.getObject();
    return response;
}

I can confirm that this block is entered and that there actually is data in the cache.

I have no idea why the hits statistic isn't being updated. Any help would be appreciated!

Turns out my objects were not being serialized correctly, so when it was searching for them in the cache they were not being found.
