Looking for Lunar Anomalies, continued again

This is an agreement map of 20 different models.  Any shade of orange indicates that all 20 models agreed that this was one of the top 256 anomalies in this region.  Grayscales indicate number of models that agreed on that particular location, brighter meaning more models in agreement.

And here's the average agreement map.  Bright areas indicate strong model agreement AND a high anomaly score:

LRO dataset M1493691723RC

Lunar Anomalies #15

A large (~300 meter diameter) hexagonal-shaped crater, with a weird looking center:

LRO dataset M1493691723RC

Lunar Anomalies #14

This first image is an area about 750m by 750m.  A large shallow crater fills almost the entire area.

Center right is a very bright ejecta blanket (???) and a crater (???).  Looks slightly pentagonal.

Are those shock waves in the regolith (near the center of the image) radiating from that bright 'crater'?

Also note the pentagonal crater (lower left), and what seems to be two almost equal-sized craters one 'inside' the other (upper right).

This is in LRO dataset M1493691723RC.

Also in the same dataset but in a slightly different location:

What is that dome-looking object in the center of this crater?  At the resolution of this image (0.68 meters per pixel), this object is about 7 meters across.

This one, from LRO dataset M1493691723LC, is very confusing:

Same dataset -- there continue to be quite a number of craters with these dark areas in their centers.  This one also appears to have other internal structures:
