Bug: mismatch of "bbox" and "segmentation"

[CBCBCBCBCBCBCBCB]

Dictionary below is first images annotations information that made by pycococreator.
This link is an image what I use for explain my question.

As I know, "bbox" contains left top coordinate and right bottom coordinate.

To simple check data is fine, I printed max value of "bbox" and "segmentation".
As I understand, max value of "segmentation" and max value "bbox" have to be same.
(whatever that max value things means right bottom x or y)

but, max of "bbox" is 765 that right bottom y coordinate
and max of "segmentation" is 787.5 that point is on shoe bottom in my image.

Is this my mistake? How can I fix this?

{"bbox": [93.0, 23.0, 254.0, 765.0], "segmentation": [[320.0, 787.5, 284.0, 787.5, 260.0, 781.5, 233.0, 779.5, 227.5, 771.0, 228.5, 762.0, 233.5, 756.0, 231.0, 742.5, 227.0, 747.5, 220.0, 749.5, 210.0, 749.5, 201.0, 743.5, 196.0, 748.5, 181.0, 748.5, 169.0, 744.5, 148.5, 725.0, 141.5, 707.0, 132.0, 705.5, 122.0, 699.5, 107.5, 680.0, 107.5, 671.0, 115.0, 661.5, 136.0, 648.5, 152.0, 645.5, 153.5, 638.0, 164.0, 631.5, 176.0, 616.5, 204.5, 593.0, 206.5, 588.0, 203.0, 571.5, 196.0, 578.5, 187.5, 575.0, 187.5, 571.0, 195.5, 562.0, 195.5, 557.0, 186.0, 545.5, 157.0, 549.5, 149.5, 542.0, 151.5, 528.0, 144.5, 510.0, 144.5, 493.0, 132.5, 455.0, 129.5, 418.0, 132.5, 374.0, 118.5, 316.0, 109.5, 298.0, 103.5, 267.0, 97.5, 256.0, 92.5, 235.0, 93.5, 218.0, 110.5, 188.0, 136.0, 163.5, 144.5, 161.0, 140.0, 159.5, 133.5, 150.0, 134.5, 129.0, 127.0, 126.5, 112.5, 108.0, 112.5, 101.0, 116.5, 95.0, 115.5, 75.0, 119.5, 70.0, 119.5, 59.0, 146.0, 30.5, 166.0, 22.5, 190.0, 23.5, 215.0, 30.5, 246.5, 65.0, 247.5, 107.0, 253.5, 124.0, 250.5, 159.0, 244.0, 166.5, 226.0, 173.5, 221.5, 181.0, 232.0, 183.5, 245.5, 193.0, 272.5, 237.0, 291.5, 257.0, 299.5, 270.0, 303.5, 284.0, 303.5, 304.0, 299.5, 324.0, 291.5, 341.0, 313.5, 397.0, 324.5, 416.0, 335.5, 428.0, 333.5, 443.0, 322.5, 455.0, 330.5, 491.0, 338.5, 508.0, 337.5, 516.0, 333.0, 519.5, 324.0, 519.5, 320.5, 529.0, 321.5, 539.0, 330.5, 555.0, 331.5, 571.0, 323.5, 583.0, 297.5, 605.0, 292.0, 617.5, 270.5, 621.0, 269.5, 634.0, 274.5, 651.0, 269.5, 657.0, 267.5, 672.0, 268.5, 693.0, 280.5, 727.0, 288.0, 729.5, 296.0, 741.5, 303.0, 741.5, 309.0, 736.5, 317.0, 737.5, 333.0, 755.5, 341.0, 756.5, 346.5, 763.0, 346.5, 768.0, 339.0, 778.5, 320.0, 787.5]], "area": 114927, "id": 1, "category_id": 1, "height": 1080, "image_id": 1, "iscrowd": 0, "width": 1920}

can you share the original image and the binary mask of the person, so I can try to reproduce the issue?

Could you mail me? or is there any other options to send my image to you?
