Overlapping items in development / evaluation / validation sets

Hi, thanks for the great work!
I'm new to the dataset; and I found out there are overlapping entries between split sets as below.

Between valid and eval sets:

• sound_id 66304. In valid set, the segment is [1607168, 2436248]. In eval, it's [1597440, 2865471].
  • file name: 01 A pug struggles to breathe 1_14_2008.wav
• sound_id 86161. [263168, 1253213] vs [173056, 1249146].
  • file name: Bus(Drive_Reverse)_1-2.wav

Between valid and dev sets:

• sound_id 86163. Its whole segment was used in both.
  • file name: City Ambience w_ Car Passing_1-2.wav
• sound_id 130603. [0, 822465] vs [11264, 768067].
  • Their file names vary. (Greek Chat2 - (Apollonia__39_s sPA) 18_44 05.10.wav // Greek Chat2 - (Apollonia's sPA) 18_44 05.10.wav)

Between eval and dev sets:

• soind_id 137692. [635904, 1430834] vs [141824, 1370009].
  • FREEZER_DOOR_OPEN_CLOSE.wav

I'm now wondering if this is a known issue to the (DCASE?) community / researchers. If so, do you know what is the recommended way to handle this? Otherwise, perhaps it's something that can be updated in Clotho 2.2 or something.
