Why can't djnago see some of the pictures from the same folder?

Question

Django

Good day
, please tell me why django does not see some of the pictures from the folder, if it sees others from the same folder?

Here is the code from settings.py

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.2/howto/static-files/
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')

#STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR,'static')
]

For example, he sees this

<img src='{% static 'img/sword.png' %}' width='22' height='22' alt=''>

but this is not

<img src='{% static 'img/ad.png' %}' width='24' height='24' alt=''>

Of course {% load static %}, in the header

And by the way, in the console it does not display any information about the picture that I cannot display, although it loads the rest of the folder, even those that are not, though 404, but still
