### 📝 Description

Hi there,

I recently migrated to v2.0.2, migration when nicely (took a long time but eventually finished without issues) and then I used [kumadb-migrator](https://github.com/cmauf/kumadb-migrator) to move data to a mariadb database. Everything seemed to work correctly and I let i run. Not sure it is related to my issue but I put it there just to have the whole picture.

The issue is, since v2.0.2, I have a couple of PUSH monitors that are monitoring a daily job. The heartbeat duration is set to 1 hour 25 retries. But event when an UP heartbeat is pushed the retries are still incrementing until the monitor goes DOWN.

Here is what it looks on the dashboard:

### 👟 Reproduction steps

- Migrate to v2.0.2
- (maybe move to mariadb)


### 👀 Expected behavior

Same behaviour that I had before v2. As soon as the UP heartbeat is pushed, the retry counter should be reset.

### 😓 Actual Behavior

The retry counter sometimes still keep counting event though an UP heartbeat is registered.

Here is the database extract where the heartbeat `27383803` does not reset the **retries** counter.

```
MariaDB [kumadb]> SELECT * FROM heartbeat WHERE monitor_id = 92 ORDER BY end_time DESC LIMIT 100;
