Issue with automatic 2D zone detection for HMBC samples.

We are encountering two issues related to HMBC samples:

1. Excessive Zones in Auto Detection (HMBC.jdf – Auto-processed by NMRium)

For the HMBC.jdf sample (auto-processed by NMRium), running automatic zone detection generates an unexpectedly large number of zones. This seems abnormal compared to typical HMBC datasets.

2. Errors with HMBC Sample (Auto and Manual Detection)

With another HMBC sample, we encounter the following issues:
During automatic zone detection:
```
RangeError: Invalid array length
```
During manual zone detection:

```
TypeError: Cannot read properties of undefined (reading 'map')
```

These errors prevent both automatic and manual zone detection from completing successfully.
