Please include examples in the message text or as a text attachment.
Images are not helpful, since they require people to retype your
example (or use OCR), instead of cutting and pasting.

I cannot reproduce your problem:

sh-4.2$ cat /etc/redhat-release 
CentOS Linux release 7.9.2009 (Core)
sh-4.2$ rpm -q gawk
gawk-4.0.2-4.el7_3.1.x86_64
sh-4.2$ echo "beeeeet" | gawk '/be{1,3}t/ {print $0}'
sh-4.2$ 

How does your environment differ?
