overlapping subnet problem.

Good afternoon, I am having issues with an assignment for school that asks me to change my topology subnet completely. They give the example 192.168.200.0 and I am going with 192.168.44.0/26 I used Solarwinds online advanced subnet calculator to make 5 subnet IP ranges for the 5 different sections of my network but every time I go into a router for instance and on gig/8 I input 192.168.44.1 then for the next subnet I do 192.168.44.8/29 it is saying overlapping address and if I used the calculator why would it be giving me overlapping address?

Feel free to message me to explain as well, and I can even jump on discord but can not find a youtube video solving my issue.

Here is the response from solarwinds:

192.168.44.0/26 (255.255.255.192)

(8 subnets)

(6 addresses per subnet)

1st =router

2nd=sales

3rd=engineering

4th=manufacturing

6th=wifi
