Conflict with 2 Omnitik in the same switch

Hi, I have 2 Omnitik in a tower. In the base, I have a comon switch (4 ports), and the 2 omnitik are connected in the switch. There is the problem. I think they are in conflict by the switch. When 2 omnitik are in the switch only one is detected and working. But when I disconnect from the switch the other, it works. When I try without the switch, each one works perfectly. But the problem is when the 2 omnitik are in the same switch. I think is a conflict. But I think that may be a configuration. Please if someone know the solutions I will thanks.

Make sure the two OmniTiks are using different, unique, IP addresses in the same subnet on the interfaces with connect to the switch.
Or do you have some non-IP level conflict? You have not actually told us what the conflict symptoms are.

Hi Lambert. Yes, the 2 omnitik have different IP. 1 is 192.168.97.120 and the other is 192.168.97.121
The conflict symptoms is that only works 1 omnitik. With winbox I dettect 1 omnitik, and their cpe connected to it. If I disconnect it from the switch, I dettect the other omnitik with winbox. But always only 1 omnitik.
All CPE connect to omnitik have different IP.
The only solution that I found is add another switch.
I have optical fiber, and then modem router, that works like a switch.
I attach 3 graphics to explain better. 1 and 2 don´t work. The only way that work is the 3.
The 2 CPE SXT never had problem. They work perfect. All equipment are in bridge mode
Thank Lambert

Can you show us screen captures of winbox trying to discover all of the devices in each of the three cases?
Did you originally setup one OmniTik; then back that configuration up and restore its configuration on the second OmniTik; then change the IP addresses on the second OmniTik to be unique?
If that happened, I wonder if the MAC addresses were cloned between the two of them and some form of STP is turning off the second switch port when the switch sees the same MAC address on two ports. Just a wild guess.
The winbox screen captures should show us the MAC addresses of all of the devices.
What model are the switches and modem/routers?
