and I'm doing much the same: a Raspberry Pi running Raspbian, acts as my nameserver (instead of my ISP) and NTP server. all the systems in-house sync time from it.

What IS in your chrony.conf file?
"pool.ntp.org" is not a single server. It is a collection of several dozen. When you specify a pool of servers for chrony, it will pick 4 mostly at random and use those. The four servers it chooses will change over time.
If you want to use exactly one specific server, then take the pool out of chrony.conf and add your specific server. I do not see a way for chronyc to remove servers, so it is a matter of editing the file directly and then restarting chronyd.
In my case, only my internal master server goes against a pool. All other internal systems use the internal master as their only source. Sometimes when I do "chronyc sources" on them, I see the server listed twice. After investigation I found that one is for IPv4 and the other for IPv6.

Thanks everyone for the comments. So trying to use the new "chronyc/d"
So trying a couple things with chronyc
chronyc sources 210 Number of sources = 5 MS Name/IP address Stratum Poll Reach LastRx Last sample
===============================================================================
^* time.cloudflare.com 3 10 377 220 -481us[ -503us] +/- 17ms ^- zeit.arpnetworks.com 2 9 377 452 -1083us[-1104us] +/- 100ms ^- lofn.fancube.com 2 10 377 851 -1833us[-1854us] +/- 64ms ^- ntp3.junkemailfilter.com 2 9 377 227 -937us[ -959us] +/- 76ms ^- b.st1.ntp.br 1 6 377 56 -2300us[-2300us] +/- 79ms
NONE of the above are listed in /etc/chrony.conf
Then I tried "chronyc add server pool.ntp.porg" and ran "chronyc sources" again and my server was not added ?
I am trying to use the command line chronyc - to "add" the server I want
also wish there was an EASY way to clear the server list. Have not seen that though.
What I need is a way to add the server i want - list the server to make sure my server is in the list - and remove servers I dont want (or all).
Thanks,
